AI as Analysis Partner, Not Analyst
AI excels at the mechanical parts of data analysis: writing code, choosing appropriate tests, generating visualizations, and explaining results in plain language. It fails at the parts that require scientific judgment: deciding what questions to ask, interpreting results in domain context, and distinguishing real effects from artifacts. The workflow is conversational but disciplined: 1. You describe your data and research question 2. AI generates analysis code 3. You run the code on your actual data 4. AI helps interpret the output 5. You validate the interpretation against your domain knowledge The critical principle: **AI writes code, your computer runs code, you interpret results.** Never accept AI-generated numbers as results. They must come from code executed on your actual data.
The fabrication risk: If you ask "what is the correlation between X and Y in my data?" without providing the data, the model will fabricate a plausible answer -- complete with r-values, p-values, and confidence intervals. These numbers are fiction. Always provide your data or have AI generate code that computes the answer from your data.
Exploratory Data Analysis with AI
Start every analysis with EDA. AI accelerates this by generating comprehensive exploration code from a data description. ```python EDA_PROMPT = """ I have a dataset with these columns: {column_descriptions} The dataset has {n_rows} rows. Here are the first 5 rows: {sample_rows} Generate a complete EDA script in Python (pandas + matplotlib + seaborn) that: 1. Shows summary statistics for all numeric columns 2. Checks for missing values and their patterns 3. Plots distributions for each numeric variable 4. Generates a correlation matrix heatmap 5. Creates scatter plots for the most correlated variable pairs 6. Identifies potential outliers using IQR method 7. Checks for class imbalance in categorical variables Include comments explaining what each section checks and why. """ ``` After running the EDA code, share the output with the AI for interpretation: ```python INTERPRET_PROMPT = """ Here are the EDA results for my dataset on {topic}: Summary statistics: {stats_output} Missing value report: {missing_output} Correlation matrix (top pairs): {correlation_output} Given my research question ("{question}"), what patterns are noteworthy? What potential issues should I address before formal analysis? What follow-up analyses would you recommend? """ ```
Data privacy: Before sharing data with AI, check your IRB protocol and data use agreement. If your data contains PII or protected health information, anonymize it first or describe the data structure without sharing actual values. Most AI providers state they do not train on API data, but your IRB may require additional safeguards.
