What do strong data analyst bullet points look like?

Strong data analyst bullets show the question you answered, the tool you used and the decision or result that followed. Analysis only matters when someone used it.

Examples (fictional, adapt to your work):

• "Wrote SQL queries joining sales, returns and web data to find the product lines driving most refunds; the category team changed two suppliers."
• "Automated a monthly KPI report in Power BI, cutting preparation from two days to two hours."
• "Built a customer churn model in Python that flagged at-risk accounts for the retention team each week."
• "Cleaned and merged five years of branch data in Excel and Power Query to support a store-closure review."

Avoid bullets that only say "analysed data" or "created reports". Say which data, for whom and what changed.
