5, 7, 7, 7, 8, 10, 12, 15, 20, 22 What is the interquartile range of this data set?

Answer 1

Explanation:

UQ: equation is n+1/4*3

So 10+1 is 11 11/4 is 2.75 2.75*3 is 8.25th data

UQ is 15

LQ: Equation is n+1/4

So 10+1 is 11 11/4 is 2.75th data

LQ is 7

IQR= UQ-LQ

so 15-7 is 8

IQR is 8

Hope this helps!!!!

Have a nice day:)
