    Answer:

    4.4

    Step-by-step explanation:

    Data set = 79, 93, 92, 86, 90

    Xmean = (79 + 93 + 92 + 86 + 90)/5

    = 440/5

    Xmean = 88

    MAD =

    (79 – 88) + (93 – 88) + ( 92 – 88) + ( 86 – 88) + ( 90 – 88)/ 5

    =

    (9) + (5) + (4) + (2) + (2)/ 5

    =

    22/5

    Mean Absolute Deviation = 4.4

    Answer:

    The MAD is 4.4.

    Step-by-step explanation:

    1. 79+93+92+86+90/5= 88= Mean.

    2. Apply |values – mean| 9+5+4+2+2=22

    3. Divide by total of values, 22/5= 4.4.
