When do we use the average range instead of the average moving range?

  1. Nov 24, 2013 #1
    1. The problem statement, all variables and given/known data



    2. Relevant equations

    =̿+2̅, =̿−2

    =4̅, =3̅

    3. The attempt at a solution

    From what I gather, we can use the sample range, which is the max minus the min, or the average moving range which is the sum of the preceding value minus the current value divided by the number of moving ranges.

    For the equations mentioned above, can we use any one of them or can we just use the average of moving ranges?

    What does R stand for, average moving ranges or sample range or both?
