Question

Find the mean, median and mode for the following data:

Answer 1

Mean=21.5 (addition of all numbers, divided by total number=129/6)
Median=22.5 (middle number, since there are two add them both and divide)
Mode=24 (most occurring number)

If I understand the second part of the question you would have #3 as your choice.
