Match the values with the statistical measures for these data points. 20, 20, 21, 22, 23, 23, 24, 24, 25, 25, 26, 26

20, 20, 21, 22, 23, 23, 24, 24, 25, 25, 26, 26

Step-by-step explanation:

median (middle number) is (23 + 24) / 2 = 47/2 = 23.5 <== median

Q1 = (21 + 22) / 2 = 43/2 = 21.5 <== lower quartile

Q3 = (25 + 25) / 2 = 50/2 = 25 <== upper quartile
