School A 24 21 23 22 22 21 20 23 22
School B 5 3 2 5 20 12 3 4 3


Part A: How can you use box plots to compare the median and interquartile range of the data? Write the minimum value, first quartile, median, third quartile, and interquartile range for the two sets of data.

Part B: Are the box plots symmetrical in shape? Justify your answer.

Answer 2

Part A:

You can create box plots to compare the data because it shows you the values easily, so u can easily tell if either medians or IQR's are greater than eachother or not.

School A:
Minimum value:20
First quartile:21
Median:22
Third quartile:23
Interquartile range:2

School B:
Minimum value:2
First quartile:3
Median:4
Third quartile:5
Interquartile range:2


Part B:

School A is symmetric but School B is not.
