Question

What number of students describes the third quartile?
20, 18, 21, 18, 22, 24, 18, 23, 23, 24,

Answer 1

Explanation:

Arrange the numbers in order from least to greatest;

18, 18, 18, 20, 21, 22, 23, 23, 24, 24

Find the Median = (21+22)/2= 21.5

Find the median (Q1) between 21.5 and 18 = 18

Find the median (Q2) between 21.5 and 24 = 23
