    It's a procedure. It's not a mystery. :-) 1) Calculate the mean. 2) Calculate the deviation from the mean for each observation. 3) Find the absolute values of the deviations. 4) Add up all the absolute deviations. 5) Divide by the number of observations. Done.

    Okay. Is that correct. I didn't do it. I'm hoping you did. If you did it correctly, and you managed Choice "D", then that's awesome. Since you showed none of your work, I can't verify that.

    I did 2+10+16+21+27+38=114 divided by 6=19

    Why did you just use the values? Please use the procedure shown. 1) Calculate the mean. 2) Calculate the deviation from the mean for each observation. 3) Find the absolute values of the deviations. 4) Add up all the absolute deviations. 5) Divide by the number of observations.

    That was calculating the mean. Now do the rest.
