Page 5 of 7 5. (2 points) Considering the boxplot in Figure 1, determine (rounding to nearest integer is o.k.) Figure 1: Question 4 (a) The median (b) The First Quartile (c) The Second Quartile (d) The mximum value

Solution

(a) The median = 5.0

(b) First Quartile Q1 = -2.5

(c) Second Quartile Q2 = 5.0

(d) The maximum value Q3 = 12.5

(e) Inter-quartile range IQR = Q3 - Q1 = 12.5 - (-2.5) = 15.0
