COMPARING THE DISTRIBUTION OF BOX PLOTS

Compare the distributions of each pair of box plots below.

Problem 1 :

Solution :

Comparing median will give the best result.

Median of 7A = 20

Median of 7B = 28 (approximately)

By comparing the median, it is clear, performance of 7B is good.

Problem 2 :

Solution :

Median time taken to complete the puzzle for children = 8

Median time taken to complete the puzzle for adults = 15

So, adults are taking much time to complete the puzzle.

Problem 3 :

Solution :

Median length of red squirrels = 21

Median length of grey squirrels = 26

So, average length of grey squirrels are greater.

Problem 4 :

Solution :

Median reaction time of group A = 0.3

Median reaction time of group B = 0.3

So, reaction time of both groups are same.
