Question

The two box and whisker plots below show the times in seconds for two teams in a 100m dash . What do the interquartile ranges tell you about the two teams

Answer 1

The first box plot shows the value of Q1 = 32 and Q3 = 37. Hence the Interquartile range = 37-32 = 5

The second box plot shows the value of Q1 = 29 and Q3 = 36, Hence the interquartile range = 36-29 = 7

Team B has bigger interquartile range than team A and it shows that the data spreads more than Team A's

It also shows that Team A's scores are more consistent
