Question

Create a comparative box plot for the morning and afternoon dogs, and label each with its five-number summary. (6 points: 3 points for the correct form of plot, 3 points for appropriate labels)

Answer 1

A labelled comparative box plot for the morning and afternoon dogs is shown in the picture attached below.

In order to determine the five-number summary for the morning and afternoon dogs, we would re-arrange the data set in an ascending order (from least to greatest).

Based on the data set representing the morning dogs, we can logically deduce that the five-number summary are as follows;

12, 19, 19, 21, 23, 25, 27, 31, 36, 39

Minimum value = 12

Lower quartile = 19

Median = (23 + 25/2 = 24

Upper Quartile = 31

Maximum value: 39

Based on the data set representing the afternoon dogs, we can logically deduce that the five-number summary are as follows;

8, 8, 11, 15, 16, 27, 34, 39, 43, 51

Minimum value = 8

Lower quartile = 11

Median = (16 + 17)/2 = 21.5

Upper Quartile = 39

Maximum value: 51
