Match the values with the statistical measures for these data points. 20, 20, 21, 22, 23, 23, 24, 24, 25, 25, 26, 26 tiles 22.5 25 23.5 21.5 23 pairs upper quartile lower quartile median

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

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

The linear equation is: y=ax+b
