Question

The table below shows the number of students from different classes of two schools who participated in a sports competition:



School A 25 21 2 22 20 21 20 23 1
School B 3 2 1 5 4 2 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. (5 points)

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

Answer 1

i need help
don't know how to do this

Answer 2

The median is the middle number, so you need to first aline the numbers in numeric order. (ex. 1,2,3...) After you do that, then you can find the middle number. Minimum value simply means the smallest number. The first quartile is simply the median of the first half of the numbers (keep them in order) The third quartile is the median of the second half. Then to find the interquartile, you take the medians of the first and third quartile and subtract them.

Answer 3

Part B- I would think that you would have to graph them or if you have a picture use that.
