Question

If you are working out the mean, with a set of 16 numbers but in those numbers there are doubles do you still include them in the working out???
for example: the numbers are:
250, 250, 180, 180, 310, 276, 116, 90, 312, 700, 239, 165, 221, 243, 350, 536.

do you include the second 250 and 180? or only use one ???

Answer 1

Yes, you still include them.

For example the 3 numbers:

2, 2, 5

The mean is:  (2+2+5) ÷ 3 =  9 ÷ 3 = 3
