Answer:
The median score of class A is 73
The interquartile range of class B is 8 
The difference of the medians of class A and class B is 9
the interquartile range of either data set should be 8 because that is what b was. 
Step-by-step explanation:
The interquartile range is the difference between the upper quartile and the lower quartile. In example 1, the IQR = Q3 – Q1 = 87 - 52 = 35. The IQR is a very useful measurement. It is useful because it is less influenced by extreme values as it limits the range to the middle 50% of the values.
