This lesson focuses on understanding and interpreting box plots, along with calculating and analyzing median and interquartile range (IQR). Students are presented with various scenarios involving data sets where they must compare prices, analyze test scores, and evaluate waiting times based on box plots. The exercises encourage them to think critically about whether the median or the range better represents data differences, as well as how to derive Q1, Q3, and IQR from provided datasets. Additionally, students are tasked with creating their own box plots and determining statistical measures from visual data representations.
