Question

PLEASE HELP! MEDAL AND FAN! PROMISE!
The table below shows the number of students from different classes of two schools who participated in a debate:

School A 24 18 2 22 19 21 20 23 1
School B 3 2 1 5 14 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 1

You will have to draw the box plots. Can you do that? You will need some Medians.

Answer 2

not really :/

Answer 3

I'll do one. You do the other.

Step #1 - Sort your data.

1 2 18 19 20 21 22 23 24 - There are 9.

Step #2 - Pick the Median or Middle value.

20 has four values on one side and four on the other. 20 is the median

Step #3 Find the median of the remaining left-hand numbers

1 2 18 19 - Somewhere between 2 and 18?

Okay, this is where we have to stop and have a little discussion. What do we do when there are an even number of points. Some want the average of the two inside points. Some want us to pick something in the dataset. There MUST be a definition somewhere in your course materials. We cannot continue until we know what it wants.
