    a) Substitute the data into the usual formula.

    b) Order the data from smallest to biggest and get the median (which is Q2).

    c) Substitute your answer to a) and the data into the usual formula.

    Quick question.. For finding the mean deviation, I have a set with duplicate numbers. Should I count both 7's as single? Or include them as one number.

    So.. Instead of there being 10 numbers in the set, there would be only 8?
