Transcript
[0:00]Adrian: Welcome back to the Data Analysis Stack podcast, where we explore the real work of turning raw data into actionable insights. I’m your host, Alex, and today I’m thrilled to dig deeper into what makes data analysis tick in the real world. Our guest is Dr. Mia Chen, Principal Data Scientist at Insightful Analytics Group. Mia, welcome to the show!
[0:18]Dr. Mia Chen: Thanks, Alex! I’m excited to be here. Data analysis is one of those topics that gets more fascinating the deeper you go, so I’m looking forward to our conversation.
[0:34]Adrian: Absolutely. Let’s set the stage: When people hear 'data analysis', they might picture clean spreadsheets or automated dashboards, but that’s rarely the reality. How would you define data analysis in practice?
[0:52]Dr. Mia Chen: In practice, data analysis is about making sense out of imperfect, often messy data to drive better decisions. It goes beyond running formulas—it’s about understanding the context, making trade-offs, and asking the right questions, even when the data is far from ideal.
[1:10]Adrian: That resonates. Maybe let’s dig into that messiness a bit. Can you describe what a typical raw dataset looks like before any cleaning?
[1:28]Dr. Mia Chen: Sure! Most raw datasets have missing values, typos, different formats, or even contradictory entries. For example, I’ve seen sales data where dates are mixed up, currencies aren’t standardized, or the same customer appears in multiple ways. It’s rarely plug-and-play.
[1:50]Adrian: So the first big hurdle is just getting a sense of what’s there. What’s your go-to approach for assessing data quality at the start?
[2:08]Dr. Mia Chen: I start with basic profiling—looking at distributions, checking for missing or extreme values, and scanning for duplicates. Tools like pandas in Python or dplyr in R make this easier, but the key is to always visualize before diving deeper. Patterns often jump out that way.
[2:26]Adrian: Let’s pause and define profiling for listeners who might be newer. When you say profiling, what do you mean?
[2:37]Dr. Mia Chen: Profiling is a first-pass scan of your dataset to get summary statistics, like counts, means, or unique values for each column. It helps you spot things like columns that are mostly empty or categories that don’t make sense.
[2:50]Adrian: Great. So once you’ve profiled the data, how do you decide what kind of cleaning is needed?
[3:03]Dr. Mia Chen: It depends on the context and the questions you’re trying to answer. Sometimes you can safely drop rows with missing data, other times you need to impute values or reach out to the data source to clarify. You have to balance data integrity with practicality.
[3:18]Adrian: That’s a real judgment call. Have you ever faced a situation where cleaning the data actually introduced new problems?
[3:32]Dr. Mia Chen: Absolutely! One time, we automatically filled missing product categories with 'Unknown', thinking it was harmless. But later, those 'Unknowns' made it hard to segment our analysis, and we realized we’d lost some nuance that was important for the business.
[3:50]Adrian: That’s such a common mistake—fixing the data on the surface, but masking underlying issues. Let’s talk about the art of choosing the right analytic method. How do you approach that decision?
[4:08]Dr. Mia Chen: It starts with understanding the business problem. For example, if you’re looking to predict churn, you might use logistic regression or a decision tree. But if you just need to summarize trends, a few well-chosen aggregations and visualizations might be enough. The best approach is the one that fits the question and the data.
[4:28]Adrian: That’s an important point. People sometimes reach for complex models when a simple chart would do. Have you seen that play out?
[4:44]Dr. Mia Chen: All the time. There’s a temptation to use machine learning for everything, but sometimes a basic pivot table tells the story more clearly. Recently, a team spent days training a model to forecast sales, but a simple rolling average captured the trend just as well.
[5:02]Adrian: Let’s dig into that trade-off between speed and rigor. How do you balance the pressure to deliver fast with the need to be statistically sound?
[5:20]Dr. Mia Chen: It’s tough. In production environments, there’s rarely time for perfect analysis. I focus on getting a quick, rough answer first—what some call a 'minimum viable analysis'—then iterate and add rigor if needed. The trick is communicating the limitations clearly up front.
[5:38]Adrian: Minimum viable analysis—I like that phrase. Can you give an example?
[5:50]Dr. Mia Chen: Sure. Once, we needed to know if a marketing campaign was working within a week. So, we quickly compared sales before and after the campaign, even though it wasn’t a controlled experiment. It gave us a signal, and later we dug deeper to rule out other factors.
[6:08]Adrian: That’s practical. But do you ever worry that a quick answer might lead people to the wrong conclusions?
[6:22]Dr. Mia Chen: Definitely. That’s why it’s crucial to document assumptions and caveats. I’ll say, 'This is a first look, not a final answer.' It’s about setting expectations and making it clear what the analysis can and can’t say.
[6:38]Adrian: Let’s shift gears and talk about tools. With so many out there—Python, R, SQL, visualization tools—how do you choose?
[6:54]Dr. Mia Chen: It depends on the data and the team. For heavy data wrangling, I like Python with pandas or R with dplyr. SQL is essential for querying databases. For visualization, tools like Tableau or Power BI are great, though sometimes a quick matplotlib chart is enough.
[7:12]Adrian: Do you ever see tool debates get in the way of progress?
[7:25]Dr. Mia Chen: Oh, absolutely. Sometimes teams argue over the 'best' language or platform, but in the end, what matters is getting answers. It’s easy to get distracted by tooling instead of focusing on the analysis itself.
[7:40]Adrian: Let’s bring in a case study. Can you share an example where the choice of analytic approach really changed the outcome?
[7:58]Dr. Mia Chen: Definitely. We worked with a retailer that saw a sudden drop in sales. They initially wanted sophisticated anomaly detection, but we started with basic time series plots. It turned out a major holiday was missing from the promotional calendar—something a simple chart revealed instantly.
[8:18]Adrian: That’s a great reminder that sometimes the simplest tool gives the clearest answer. Did the team learn anything from that experience?
[8:32]Dr. Mia Chen: They did. They realized they needed to bring domain knowledge into the analysis, not just look at numbers in isolation. It led to better collaboration between marketing and analytics.
[8:44]Adrian: Speaking of domain knowledge, how important is it to involve subject matter experts in data analysis projects?
[8:58]Dr. Mia Chen: It’s critical. Analysts can spot patterns, but only subject experts know what makes sense in context. I always try to involve stakeholders early, especially during exploratory analysis. It saves a lot of backtracking.
[9:14]Adrian: How do you handle situations where the data suggests something that contradicts what the business expects?
[9:28]Dr. Mia Chen: That’s always tricky. I approach it with humility—show the data, ask for feedback, and try to uncover why there’s a mismatch. Sometimes it’s a real issue, other times it’s a data artifact. Open dialogue is key.
[9:44]Adrian: Let’s talk about common mistakes. What’s one you see a lot, especially among newer analysts?
[9:58]Dr. Mia Chen: One big one is confirmation bias—looking for patterns that confirm what we already think. I encourage teams to actively search for evidence that contradicts their initial hypothesis, not just support it.
[10:12]Adrian: That takes discipline! Are there practical ways to guard against that bias?
[10:26]Dr. Mia Chen: Yes. One useful technique is to do 'blind analysis', where you withhold labels or outcomes until you’ve made your initial observations. Also, peer review helps—having someone else review your code or charts often surfaces assumptions you didn’t notice.
[10:42]Adrian: Let’s spend a minute on exploratory versus targeted analysis. How do you decide which to use?
[10:56]Dr. Mia Chen: Exploratory analysis is about letting the data guide you—looking for interesting patterns or outliers without a fixed hypothesis. Targeted analysis starts with a specific question. The choice depends on the business need and how well you understand the problem.
[11:10]Adrian: Can you give an example of each from your experience?
[11:22]Dr. Mia Chen: Sure. Exploratory: We once explored user engagement data without any hypothesis and discovered a spike in activity linked to a new feature, which nobody expected. Targeted: Another time, we specifically tested if a price change led to higher retention—that was a focused, hypothesis-driven analysis.
[11:40]Adrian: Let’s pivot to automation. When is it a good idea to automate parts of the analysis?
[11:54]Dr. Mia Chen: Automation shines when you have repetitive tasks, like generating weekly reports or refreshing dashboards. But you have to be careful—it can lock in bad assumptions if you’re not monitoring regularly.
[12:08]Adrian: Have you seen automation go wrong?
[12:22]Dr. Mia Chen: Yes! Once, we automated a report that relied on a data feed which changed structure. The charts looked fine, but the numbers were off for weeks before anyone noticed. Regular manual checks are still important.
[12:38]Adrian: That’s a hard lesson. Let’s talk about communicating results. What’s your approach to making findings clear to non-technical audiences?
[12:52]Dr. Mia Chen: I try to tell a story—start with the business question, explain what we found, and what it means for decision-making. I use clear visuals and avoid jargon. If the audience can’t act on the findings, the analysis isn’t done.
[13:08]Adrian: Have you ever had a visualization mislead instead of clarify?
[13:22]Dr. Mia Chen: Yes, sometimes a chart exaggerates a small effect, especially if axes aren’t set properly. For example, we once showed a drop in sales that looked dramatic, but it was only a 2% decline. After adjusting the axis, it was much less alarming.
[13:38]Adrian: Let’s pause and define that for newer listeners—what’s the risk with playing with axes?
[13:50]Dr. Mia Chen: Adjusting axes can make small changes look huge, or vice versa. Always show the full context, so viewers can see if a change is meaningful.
[14:02]Adrian: Let’s bring in another mini case study. Can you share a story where poor data quality derailed a project?
[14:18]Dr. Mia Chen: Definitely. A company was launching a new product, and all the forecasts looked great. But after launch, sales lagged. Digging in, we found that the initial analysis had used outdated customer data, missing a shift in their main audience. The lesson was to always check your data sources, especially if it’s been a while since the last pull.
[14:38]Adrian: That’s such an important lesson—data can go stale. How do you build in checks to prevent that sort of thing?
[14:50]Dr. Mia Chen: We set up regular data audits and always document where each variable comes from and when it was last updated. It’s extra work, but it saves you from nasty surprises.
[15:04]Adrian: Let’s talk about collaboration. How do you get analysts and stakeholders on the same page?
[15:16]Dr. Mia Chen: Frequent check-ins help, and involving stakeholders early. Even a quick 15-minute sync can clarify expectations and surface new questions you might not have considered.
[15:28]Adrian: Sometimes, do you find disagreements over how to interpret the data?
[15:40]Dr. Mia Chen: Yes, and that’s healthy. Different perspectives can shed light on blind spots. If we disagree, I like to lay out the evidence on both sides and consider what additional data could resolve things.
[15:54]Adrian: Have you ever had to defend your analysis against a strong alternative viewpoint?
[16:10]Dr. Mia Chen: Definitely. Once, a stakeholder insisted a drop in engagement was due to a site redesign, but the data pointed to a seasonal effect. We compromised by running a cohort analysis, which showed both factors played a role. Sometimes the answer isn’t either-or.
[16:28]Adrian: I like that—it’s not about being 'right' but about getting to the truth. Let’s shift to documenting assumptions. Why is that so important?
[16:42]Dr. Mia Chen: Because every analysis rests on assumptions—about the data, the methods, what’s missing. If you don’t write them down, it’s easy to forget or mislead others. Clear documentation makes it easier to revisit or audit the analysis later.
[16:56]Adrian: Do you have a favorite way to keep track of assumptions and decisions as you go?
[17:08]Dr. Mia Chen: I like to keep a running log, almost like a project diary. Every time I make a choice, I jot down why. It doesn’t have to be formal—just enough that someone else could follow my reasoning.
[17:22]Adrian: That’s a great practice. Let’s talk about reproducibility. In modern teams, how do you ensure analyses can be rerun and checked by others?
[17:36]Dr. Mia Chen: Using version control, like Git, helps. Also, building analyses in notebooks or scripts that can be executed end-to-end, instead of just manual steps. It’s a bit more setup, but it pays off for collaboration and debugging.
[17:52]Adrian: Do you ever get pushback on spending time to make things reproducible?
[18:06]Dr. Mia Chen: Sometimes, especially when deadlines are tight. But I argue that reproducibility saves time in the long run—less time spent figuring out what you or someone else did months ago.
[18:20]Adrian: Let’s wrap up this first half by talking about continuous improvement. How can analysis teams keep getting better?
[18:34]Dr. Mia Chen: Regular retrospectives help—after a big project, reflect on what went well and what could improve. Encourage knowledge sharing, and don’t be afraid to experiment with new tools or techniques. The field is always evolving.
[18:50]Adrian: That’s a great note to pause on. We’ll dig into more advanced topics, like ethics, automation, and handling disagreements, after the break. Mia, thanks for sharing so many practical insights so far.
[19:00]Dr. Mia Chen: My pleasure! Looking forward to the next part.
[27:30]Adrian: Alright, we’re back! Earlier, we talked about the basics and some of the foundational concepts in data analysis. I want to shift gears now and dig into the real-life application side. Let’s start by talking about what often goes wrong. In your experience, what are the most common mistakes teams make when implementing data analysis?
[27:50]Dr. Mia Chen: Great question. One of the biggest mistakes I see is skipping the data cleaning phase or underestimating its importance. Teams sometimes rush straight to modeling or visualization, but if the data is messy or inconsistent, the conclusions can be completely misleading.
[28:07]Adrian: Can you share an example of how that plays out?
[28:20]Dr. Mia Chen: Sure. There was a retail company I worked with who wanted to analyze customer purchase patterns. They dove right into clustering their customers, but didn’t realize that their transaction data had duplicates and missing values. Their segments made no sense, and they spent weeks chasing their tails before realizing the data prep step was off.
[28:44]Adrian: Ouch. So, how can teams avoid that mistake?
[28:54]Dr. Mia Chen: Document everything. Start with data profiling—look for missing values, outliers, duplicates, and inconsistencies. Make sure the business context is clear so you can spot anomalies that don’t fit reality. And always validate your cleaned data before moving forward.
[29:18]Adrian: That makes sense. Another thing I’m curious about is data-driven culture. How do teams get buy-in from stakeholders who might not be data-savvy?
[29:35]Dr. Mia Chen: It’s all about storytelling. You need to translate technical findings into clear business value. Use visuals, analogies, and real-world examples. And don’t be afraid to repeat the key message in different ways until it resonates.
[29:50]Adrian: Would you say that’s more art than science?
[30:00]Dr. Mia Chen: Absolutely. Communication is a huge part of data analysis that’s often overlooked. The best analysts can bridge the gap between numbers and business impact.
[30:17]Adrian: Let’s talk about tools. There are so many data analysis tools out there now—how should teams choose which to use?
[30:32]Dr. Mia Chen: It depends on the size of your data, your team’s skill set, and your goals. For quick exploratory work, spreadsheets or lightweight BI tools are great. For larger datasets or more complex analysis, Python or R are usually better. And for production systems, you want something scalable, like SQL-based platforms or dedicated analytics engines.
[30:52]Adrian: How about open-source versus commercial solutions?
[31:02]Dr. Mia Chen: Open-source is fantastic for flexibility and cost. But commercial tools often win for ease of use, support, and integrations. It’s not unusual to see hybrid stacks—teams might prototype in open-source, then transition to a managed platform for deployment.
[31:23]Adrian: I’d love to pivot to a mini case study here. Can you walk us through another example where data analysis made a big difference?
[31:36]Dr. Mia Chen: Definitely. There was a logistics company struggling with late deliveries. They had tons of route data but weren’t sure how to use it. We analyzed GPS traces and delivery logs, and found that a few key routes were consistently delayed due to construction and traffic patterns. By optimizing their schedules, they improved on-time deliveries by over 20% within a few months.
[32:05]Adrian: That’s a big impact. Was there any resistance to making changes based on data?
[32:16]Dr. Mia Chen: At first, yes. Drivers were skeptical. But showing them the patterns—literally mapping out the delays—made it clear it wasn’t about blame, it was about improvement. Once they saw the evidence, buy-in followed.
[32:38]Adrian: Data visualization in action. Speaking of which, what are some best practices for visualizing data?
[32:48]Dr. Mia Chen: Keep it simple and focused. Don’t overload your charts with too many variables. Use clear labels, avoid misleading scales, and always provide context. The best visualizations answer a specific question or highlight a key insight.
[33:07]Adrian: Are there visual types you think are overused or misused?
[33:15]Dr. Mia Chen: Pie charts, for sure. They’re often used when a simple bar chart would be clearer. And 3D charts—those tend to add confusion without meaningful information.
[33:30]Adrian: Let’s shift to a rapid-fire round. I’ll ask you a series of quick questions—just say the first thing that comes to mind. Ready?
[33:37]Dr. Mia Chen: Let’s do it!
[33:40]Adrian: Favorite data analysis tool?
[33:42]Dr. Mia Chen: Pandas in Python.
[33:45]Adrian: Most overrated metric?
[33:47]Dr. Mia Chen: Clicks. They don’t always translate to value.
[33:50]Adrian: Most underrated metric?
[33:52]Dr. Mia Chen: Customer retention rate.
[33:55]Adrian: Common data analysis buzzword you can’t stand?
[33:57]Dr. Mia Chen: Synergy.
[34:00]Adrian: Favorite data visualization color palette?
[34:03]Dr. Mia Chen: Colorblind-friendly palettes, always.
[34:05]Adrian: Go-to method for quick data sanity check?
[34:08]Dr. Mia Chen: Summary statistics and histograms.
[34:10]Adrian: Biggest data analysis pet peeve?
[34:12]Dr. Mia Chen: People skipping documentation.
[34:18]Adrian: Love it. Okay, back to deeper topics. What’s the role of domain expertise in data analysis?
[34:28]Dr. Mia Chen: It’s critical. You can have the best algorithms in the world, but if you don’t understand the business context, you’ll miss subtle patterns or misinterpret the results. Collaborating with domain experts helps you ask the right questions and validate your findings.
[34:46]Adrian: Have you ever seen a project fail because the data team was siloed from the business team?
[34:58]Dr. Mia Chen: Yes, more than once. One project comes to mind where the data team built a complex forecasting model for inventory, but didn’t consult the warehouse staff. The model missed key operational realities, and their forecasts were way off. Bringing in the business side earlier would have saved a lot of headaches.
[35:22]Adrian: Let’s talk about bias. How do you spot and mitigate bias in data analysis?
[35:36]Dr. Mia Chen: Start by questioning your assumptions. Look for patterns that seem too good to be true or that reinforce stereotypes. Diversifying your data sources and involving people with different perspectives helps too. And always stress-test your findings—try to break your own analysis to see where it might be fragile.
[35:55]Adrian: Do you have a favorite method or technique for validating results?
[36:08]Dr. Mia Chen: Cross-validation is great for models. For exploratory analysis, I like to split the data and see if the patterns hold in both halves. And, of course, compare with external benchmarks or known industry standards when possible.
[36:28]Adrian: What about automation? How much is too much when automating data analysis workflows?
[36:42]Dr. Mia Chen: Automation is great for repeatable tasks—things like ETL, basic reporting, or routine model training. But you can’t automate curiosity or critical thinking. You always need a human in the loop to spot the unexpected.
[37:00]Adrian: That’s a great distinction. Let’s do another quick case study—maybe something from the healthcare or finance space?
[37:15]Dr. Mia Chen: Sure, let’s talk healthcare. A hospital system wanted to predict which patients were at high risk for readmission. The initial model was accurate on paper, but missed real-world factors like patient support systems at home. By bringing in social workers and nurses during the analysis, they were able to refine the model and reduce readmission rates significantly.
[37:41]Adrian: So the lesson is, technical accuracy isn’t enough—real-world context matters.
[37:51]Dr. Mia Chen: Exactly. The most effective data analysis balances technical rigor with a deep understanding of how decisions play out on the ground.
[38:06]Adrian: Let’s talk trade-offs. What are some common trade-offs teams face in data analysis projects?
[38:19]Dr. Mia Chen: Speed versus accuracy is a big one. Sometimes you need fast answers, even if they’re not perfect. Other times, you need precision, but it takes longer. There’s also the trade-off between transparency and complexity—complex models can be powerful, but harder to explain.
[38:39]Adrian: Have you seen teams struggle with that last one—complexity versus explainability?
[38:51]Dr. Mia Chen: Definitely. For example, a credit scoring team built a deep learning model that predicted defaults very well, but they couldn’t explain why it made certain decisions. Regulators and business leaders pushed back, so they had to simplify the model to something more interpretable.
[39:17]Adrian: That’s such a common dilemma now. I want to ask about scaling data analysis. What challenges do teams face as their data grows?
[39:32]Dr. Mia Chen: Performance is a big one. Suddenly, things that worked for thousands of rows break down with millions. Data storage, compute costs, and processing times all become issues. You need to rethink your stack—consider parallel processing, distributed systems, or cloud solutions.
[39:53]Adrian: What about data governance? How do you keep things manageable as teams and data scale?
[40:06]Dr. Mia Chen: Solid data governance is essential. That means clear data ownership, access controls, naming conventions, and documentation. Without it, data silos and duplicated efforts become unmanageable fast.
[40:27]Adrian: Let’s talk about reproducibility. Why does it matter in data analysis, and how can teams ensure it?
[40:41]Dr. Mia Chen: Reproducibility means someone else—or your future self—can follow your process and get the same results. It matters for trust and for onboarding new team members. Use version control, document your steps, and try to automate as much of the pipeline as possible.
[41:01]Adrian: I want to go a bit deeper on documentation. Any tips for making it less of a chore?
[41:15]Dr. Mia Chen: Make it part of your workflow, not an afterthought. Use notebooks or scripts that mix code, commentary, and visualizations—like Jupyter or R Markdown. And share templates to lower the barrier for your team.
[41:34]Adrian: Great advice. Let’s talk about ‘data intuition’ for a second. Is that something you can develop, or is it just experience?
[41:46]Dr. Mia Chen: You can definitely develop it. The more you work with data, the easier it gets to spot anomalies, trends, or things that just feel off. But it helps to study past projects, learn from mistakes, and ask ‘why’ a lot.
[42:05]Adrian: Let’s move to a segment I call the ‘Implementation Checklist.’ I’d love for you to walk us through the key steps to set up a successful data analysis project.
[42:16]Dr. Mia Chen: Absolutely. So here’s my go-to checklist:
[42:25]Dr. Mia Chen: First, clarify the business question. What are you trying to solve? Next, gather and profile your data—look for gaps or quality issues. Clean and preprocess the data, then explore it to spot patterns or outliers. After that, choose your methods—whether it’s simple stats or advanced modeling. Validate your findings with stakeholders, document everything, and finally, present your results in a clear, actionable way.
[42:54]Adrian: Let’s break that down a bit. Step one is clarifying the business question. How do you make sure you’re solving the right problem?
[43:06]Dr. Mia Chen: Ask lots of questions. Don’t take the initial problem statement at face value. Meet with stakeholders, dig into the ‘why’, and make sure everyone agrees on the goal.
[43:19]Adrian: And when you’re profiling the data, what are some quick checks you always do?
[43:30]Dr. Mia Chen: I run summary statistics, check for missing or duplicate values, and visualize distributions. Sometimes just a few plots can reveal huge issues.
[43:44]Adrian: How do you decide which analytical methods to use?
[43:53]Dr. Mia Chen: It depends on the question and the data. Start simple—like averages or correlations—before jumping to machine learning. And always consider interpretability for your audience.
[44:05]Adrian: Once you have results, how do you validate them?
[44:16]Dr. Mia Chen: Share preliminary findings with stakeholders and domain experts. Look for feedback and challenge your own assumptions. Also, test on holdout data or compare with past results.
[44:29]Adrian: Documentation and presentation—any final tips there?
[44:40]Dr. Mia Chen: Keep documentation concise but thorough. For presentations, tailor the message to your audience and focus on actionable insights, not just numbers.
[44:55]Adrian: Love that. Before we wrap up, I’d like to ask about failure. When data analysis projects go wrong, what’s usually the cause?
[45:09]Dr. Mia Chen: It usually comes down to poor communication, unclear goals, or skipping key steps like data cleaning. Sometimes it’s because results aren’t actionable, or the wrong stakeholders were involved too late.
[45:25]Adrian: Let’s do a quick summary. Could you give us a final checklist for listeners to take away?
[45:33]Dr. Mia Chen: Sure. Here’s a quick-hit checklist:
[45:38]Dr. Mia Chen: 1. Define the business question. 2. Profile and clean your data. 3. Explore and visualize. 4. Choose the right methods. 5. Validate with stakeholders. 6. Document your process. 7. Present clear, actionable insights.
[46:01]Adrian: Perfect. Before we sign off, do you have any final thoughts for teams just starting out with data analysis?
[46:14]Dr. Mia Chen: Don’t be afraid to start small. Focus on learning, iterate often, and don’t rush past the basics. And always keep the business context front and center.

[47:07]Adrian: Alright, one last thing—we always end with a quick checklist for listeners to put into practice. Here it is:
[47:19]Adrian: 1. Always clarify your business question. 2. Dedicate time to cleaning and profiling data. 3. Don’t skip exploratory analysis—look for stories in the data. 4. Balance speed with accuracy. 5. Communicate your findings clearly. 6. Document your process and share your learnings.
