Question

The Box-and-Whisker Graph shows the heights, in inches, of children between ages of 7 and 14. Between which two numbers would we find the lower 50% of the data?

A. Between 52 and 61 B. Between 61 and 64.5 C. Between 61 and 72 D. Between 57.5 and 61

Answer 1

A. Between 52 and 61

Explanation:

In this box and whisker plot Q1 represents the first quartile or the bottom 25% of all the data(25th percentile)

Q2 represents the second quartile and represents the lower 50% of all the data 50th percentile). The middle line represents the median of the data set.

Therefore the lower 50% of the data is found between 52 (lower limit) and 62(50th percentile)
