This document discusses measures of relative standing that can be used to describe a student's test score in relation to other students, including quartiles, deciles, percentiles, percentile ranks, and z-scores. It focuses on explaining how to calculate the first (Q1) and third (Q3) quartiles. Q1 separates the lowest 25% of scores, while Q3 separates the highest 25%. The steps provided show how to determine the class boundaries and compute the exact quartile values using a grouped frequency distribution table.
