Question

. The two box-and-whisker plots below show the scores on a math exam for two classes. What 2 things do the interquartile ranges tell you about the two classes?

IF THE PICTURES ARE NOT UP RELOAD THE PAGE PLEASE!

Answer 1

The interquartile range is the difference between the upper and lower quartiles of a set of numbers. The approximate interquartile ranges for the scores of the two classes are: Class A: 89 - 66 = 23 Class B: 94 - 79 = 15 This shows that the spread in the scores of Class A is over 50% higher than the spread of the scores of Class B.


Hope this helps.
