    Find the mean deviation about the mean for the following data:
    38, 70, 48, 40, 42, 55, 63,  46, 54, 44


    space straight M. straight D. space left parenthesis top enclose straight x right parenthesis space equals space fraction numerator sum open vertical bar straight x subscript straight i minus top enclose straight x close vertical bar over denominator straight N end fraction equals fraction numerator 8.4 over denominator 10 end fraction equals 8.4
    Thus, mean deviation from the mean of the data is 8.4.

    Find the mean deviation about the mean for the following data :
    space x subscript i        5         10           15           20              25
    space f subscript i        7           4            6              3               5

    Alternative Method
    Let A = 15(assumed mean)

    Find the mean deviation about the media for the following data:
    36, 72, 46, 42, 60, 45, 53, 46, 51, 49.

    The given data in ascending order is:
    36, 42, 45, 46, 46, 49, 51, 53, 60, 72
    Total number of terms = 10    rightwards double arrow         N = 10 (even)
                         straight T subscript straight N over 2 end subscript space equals space straight T subscript 10 over 2 end subscript space equals space straight T subscript 5 space equals space 5 to the power of th space term space equals space 46
                  space space straight T subscript straight N over 2 plus 1 end subscript space equals space straight T subscript 10 over 2 plus 1 end subscript space equals space straight T subscript 5 plus 1 end subscript space equals space 6 to the power of th term space equals space 49
    ∴         Median = space fraction numerator 46 plus 49 over denominator 2 end fraction equals 47.5
