    Question No. 1:



    Using the following data: 51, 13, 46, 49, 15, 16, 19, 18, 13, 48, 25, 36, 45, 52, 25, 50, 14, 36, 21, 45, 32, 40, 23, 21, 11, 25, 16, 18, 34, 32.



    Solution:

    1) Range = Max Value Min Value

    = 52 11

    = 41



    2) 7 Classes Frequency Distribution

    First we found Class Width



    Class Width = Range / Number of Classes

    Number of Classes already given = 7

    Now put in formula

    = 41 / 7

    = 5.85

    = Round up 5.85 to 6

    = 6



    3) Relative Frequency (Column 3)

    4) Percentage relative frequency (Column 4)



    Tabulating Numerical Data

    Frequency Distribution

    Data in Ordered Array

    11, 13, 13, 14, 15, 16, 16, 18, 18,19, 21, 21, 23, 25, 25, 25, 32, 32, 34, 36, 36, 40, 45, 45, 46, 48, 49, 50, 51, 52

    Class


    Frequency


    Relative Frequency

    = Frequency of the Class Interval / Total Frequency


    %age Relative Frequency

    = Frequency of the Class Interval / Total Frequency

    11 16


    7


    7/30=0.233


    23

    17 22


    5


    5/30=0.167


    17

    23 28


    4


    4/30=0.133


    13

    29 34

    5/30=0.167


    17

    TOTAL:


    30


    1


    100



    5) The Mean

    = (Sum of Total Value) / (Number of Total Values)

    = 889 / 30
