What is the median of the following set of numbers?

121, 347, 45, 21, 300, 614, 312, 333, 421

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.

The median of the following set of numbers is 312.

if you order them from greatest to least it would look like this:

21, 45,121, 300, 312, 333, 347, 421, 614

then you just find the middle number, which in this case is 312 and that is your median
