The table below shows the number of students from different classes of two schools who participated in a workshop on conservation of the environment.

School A 23 25 4 24 25 2 24 26 22
School B 32 35 28 29 30 25 27 29 28

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. (5 points)

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

can you help with this one?

igreen · Answer

Okay, hold on.

igreen · Answer

Okay, well you have to first find the minimum value, first quartile, median, third quartile, and interquartile range for the two sets of data.

anonymous · Answer

ugh i hate this, i still dont understand

igreen · Answer

First Set of Data:

First Quartile: 13
Median: 24
Third Quartile: 25
Interquartile Range: 12

Second Set of Data:

First Quartile: 27.5
Median: 29

igreen · Answer

In the "How Much Data Display", click the drop-down box and select "Show Everything".

You have to put the values in the small box on the left, and separate them by commas.

It will tell you everything except for the Interquartile Range, which is just subtracting the Third Quartile from the First Quartile.

igreen · Answer

Anyway, that deals with Part A.

anonymous · Answer

Okay, what about the part b?

igreen · Answer

You have to look at the plots for Set A & Set B.

igreen · Answer

The website also tells you what they look like.

igreen · Answer

The answer to Part B is:

No, they are not symmetrical in shape.

Set A's Box and Whisker Plot's Box is to the right, and Set B's Box and Whisker Plot's Box is a little to the left.

Also, Set A has 2 low values which skews it to the left.
