a range tends to be a few numbers IQR is q25 to q75
meant p25 and p75 :) 8 points 8*.25 = 2, so we average the 2nd and 3rd spots 8*.75= 6, so we average the 6th and 7th spots and the range will be between those values
6, 7, 9, 10, 14, 16, 18, 20 ___ ___ 8 17 the IQR should be from 8 to 17
thanks the IQR is 9
