For school A: 2, 2, 3, 7, 10,10,14, 17, 22
School A : 2,2,3,7,10,10,14,17,22
Part A: (2 + 3) / 2 = 5/2 = 2.5
The Median is 10
(14 + 17) / 2 = 31/2 = 15.5
The IQR Is Q3 - Q1 = 15.5 - 2.5 = 13
For School B: Nope, not symmetrical. The space between the medians should be the same number.
Hope this Helps. I can explain more if you have an comments.
