Descriptive Statistics Memo

Calculate and interpret mean, median, mode, and standard deviation for a salary dataset.

The Scenario

An HR manager asks you to summarise the salary distribution for 200 employees. She does not want formulas — she wants to understand what the numbers mean for her hiring budget.

The Brief

Invent a plausible salary dataset (you may describe it rather than list 200 rows). Calculate the four descriptive statistics, then write a short memo interpreting them for a non-technical HR manager.

Deliverables

  • The four statistics (mean, median, mode, standard deviation) with your calculations shown
  • A 150-word memo interpreting what these numbers tell the HR manager about salary distribution and equity
  • One visualization you would recommend to accompany the memo and why

Submission Guidance

If the mean is much higher than the median, that tells a story. Make sure your memo tells it.
