What is the point of drawing a box plot for maths?

Question

In my coursework comparing data, it says i should do a box plot, and then explain why i have done it, and why it is relevant, but i dont know why it is relevant.

Answer 1

Wrong-o Mark! Box plots are used all of the time in statistics. I find them to be the most useful when comparing measurements taken on two or more different factors. Suppose you wanted to compare the GPA for male versus female students. It is easier to compare them using side-by-side box plots than to compare histograms or dot plots. Also, box plots show important statistics like the quartiles and extreme values. You don't get those from other displays of data.

Answer 2

It's just a way of summarising the data that you have been working with.



(PS. Nobody ever uses them)

Answer 3

To see trends (is it going up, down, constant, etc.)
