mr lopezs class had a dropdown menu with options: lower median, higher median, lower interquartile range, higher interquartile range than mrs. stewarts class.
Step1: Identify median positions
The median is the middle line of the box. Mr. Lopez’s box median is around 2; Mrs. Stewart’s is around 1.5.
Step2: Compare medians
2 > 1.5, so Mr. Lopez’s median is higher.

IQR = Q3 - Q1. Mr. Lopez’s box length (Q3-Q1) is longer than Mrs. Stewart’s.
