    (a)
    Solution:

    An array is a systematic arrangement of objects, usually in rows and columns
    .

    (b)
    Make discrete frequency distribution from the given data,
    1,2,3,2,1,2,1,3, 4,5,1,2,3,1,4,2, 2,3,2,1,4,4,4,2,1,

    Also find;
    • Cumulative frequencies
    • Relative frequencies
    Solution:

    CLASS NO. Frequencies Cumulative frequency Relative frequency
    1 7 7 0.28
    2 8 7+8 = 15 0.32
    3 4 15+4 =19 0.16
    4 5 19+5 = 24 0.2
    5 1 24+1 = 25 0.04
    Total 25 ----

    Question no.02

    (a) Find Geometric mean from the following data.
    1, 2, 3,2,4,5,4,3,4,-1,4, 3,0,1,-3, 2,4
    Solution:

    Geometric mean can not b calculated as there are some negative values and zero values present in the data.

    (b) The weight of the 40 male students at a university is given in the following frequency table:
    Weight frequency CF
    118-126 3 3
    127-135 5 3+5 =

    163-171 4 34+4 =
    172-180 2 38+2 = (equal to the sum of total frequency.. !

    Calculate median and mode from the above data.

    Solution:

    MODE:






    MEDIAN:





    Where l=145, h=8, f=12, n/2=20 and c = 17

    Put these values in formal and then calculate…

    (b) For given data calculate range and coefficient of range,
    0.035, 0.045, 0.031, 0.044, 0.032
    Solution:
    Xm=0.045
    X0=0.031
    Range: =

    Coefficient of range: =
    Put the values in the formula then calculate

    (c) Calculate an appropriate measure of dispersion for the following data.

    161-200 169
    201-240 113
    241 and above 148

    Solution:


    Question solve with quartile deviation;;;

    Quartile deviation = Q3 - Q1 / 2
