It is thought that taking math
tests in the morning results in higher grades than taking math tests in the
afternoon. Do the data represented in the box
plots below confirm this hypothesis or not?
Well, if we take a look at the box
plot for the test taken in the morning first, we can see that the median is at
approximately 87.5, whereas if we look at the scores for the tests taken in the
afternoon, we can see that the median sits at about 75 on the axis. We can therefore conclude that
since the median score for morning tests is higher than that for afternoon tests on
average, morning math test scores are higher. So therefore, in answer to the
question, what we can say is that yes taking math tests in the morning results in
higher marks than taking math tests in the afternoon.
