A clean Excel workbook filled with financial figures needs a concise descriptive summary. The job is straightforward: apply Excel-based formulas to calculate the mean, median, quartiles, and percentiles for every relevant numeric column. The file is already in good shape, so no preprocessing or data cleaning is necessary—analysis can begin right away. Deliverables • An additional worksheet (or clearly marked section) containing the requested statistics for each column • Editable formulas rather than hard-coded values so results update when new rows are added • A short note or comment block explaining the cell references used, making it easy for me to replicate the approach in future files If you feel a quick visual such as a box-plot would clarify the quartile spread, include it; otherwise stick to the numeric summary. No macro coding is required, just solid Excel know-how.
