Mathematics - Statistics - Measures of Spread - Standard deviation and variance - Calculate SD Step by Step
8 problems with progressive scaffolding: (1-2) Given deviations already calculated, find variance and SD. (3-4) Given dataset of 5 values, calculate full SD step by step (mean → deviations → squares → variance → SD). (5) Compare two datasets: which has higher SD? What does this mean? (6) Population
