    I miss a more detailed explanation,

    for instance you could supply the example

    mean (1, 2, 3, 4, 5) = 3 with

    = (1 + 2 + 3 + 4 + 5) / 5 etc.

    It seems as though the MAD function isn't working. Is there an updated function for this?

    for MAD you can use 

    mean(|x1-mean(x1)|)

    and put your list in a table under x1.
