Measuring Dispersion and Student Performance Analysis

Dispersion measures the scatter or spread of data about a central value. Methods are classified as absolute (same units as data) and relative (unit-free ratios/percentages). Absolute measures: 1. Range = Largest value − Smallest value ( $L - S$ ). Simplest but based only on extremes. 2. Quartile De...
