    Expected value of absolute value without replacement




    I'm trying to figure something out for as a curiosity of mine, and I apparently can't remember enough of my college statistics class to solve it. If I have two sets of numbers 1-15, what is the expected value of the average of the absolute value of the difference between the two?

    Non-paired data? You just want to know that absolute difference of the two?


    15 is a small sample but if normally distribution holds, a ztest or ttest statistic would give you how many std deviation they differ by.
