Practice workbook setup
Use a small table with categories, dates, and at least one numeric measure such as revenue, quantity, or score.
Practice workflow
- State the question before summarizing the data.
- Create one quick summary with totals, averages, or counts.
- Check the same result with a second method such as a PivotTable, formula, or filter.
- Write one sentence explaining what changed and one sentence explaining what to investigate next.
Quality checks
- The analysis uses the correct grain: one row per transaction, person, month, or item.
- Blank rows, text numbers, and duplicate records have been checked.
- The conclusion links back to visible evidence in the workbook.
Common mistakes
- Summarizing before checking whether the data is clean.
- Comparing totals across periods with different lengths.
- Treating a chart as proof without checking the underlying numbers.
Next actions
- Turn the result into a reusable summary block for the next reporting period.
- Add one note describing the limitation of the analysis.
Formula focus: even if this workflow is not formula-heavy, add one check cell that confirms the final output still matches the source data.
