Minimum = 7 Maximum = 48 Median = 19 $Q_{1}$ = 11.5 $Q_{1}$ = 35 IQR = 23.5
Arranging the values in ascending order, we have: Minimum = 7 Maximum = 48 Median is the middle value = 19 $Q_{1}$ is the median of values below median, hence: $Q_{1}$ = (7+16)/2 = 11.5 $Q_{3}$ is the median of values above median, hence: $Q_{1}$ = (22+48)/2 = 35 IQR = $Q_{3} - Q_{1} = 35-11.2 = 23.5$
