21, 45, 121, 300, 312, 333, 347, 421, 614,
The median is the middle number of a data set therefore you need to arrange the data is order from smallest to largest as I have done above. Then you need to find the number in the middle which is 312 in this case by finding the number which has the central position (position 5 in this case) of the data set. If there are an even number of numbers in the data set, you add them together and divide by 2 though that is not necessary this time as there are an odd number of numbers.

Because those two variables are related and student test score can be predicted using number of classes that are missed.
