Given,

  • Xi             fi

        4               12

        5               10

        6                18

        7                20

        8                24

To find,

  • We have to find the arithmetic mean.

Solution,

We can simply find the arithmetic mean by using the following formula:

                Arithmetic mean = ∑fixi/∑fi    (*)

       Xi             fi             Xifi

        4               12             48

        5               10              50

        6                18              108

        7                20               140

        8                24               192

                          84                538

∑fiXi = 538,  ∑fi = 84

Arithmetic mean = 538/84

                            = 6.40

Hence, the arithmetic mean from the following data: X: 4 5 6 7 8 frequency: 12 10 18 20 24​ is 6.40.
