    This document discusses the calculation of class intervals for income data and presents various representations of the frequency distribution of the data. It calculates the class interval to be approximately Rs. 5,000 and provides tables showing the raw frequencies, relative frequencies, a histogram, frequency polygon, and pie chart displaying the distribution of monthly incomes between Rs. 10,000-40,000 among a sample of 30 people.

    Solution:

    Calculation of class interval:


    Height monthly income = 36400
    Lowest monthly income = 10300
    Range = 26,100
    𝑅𝑎𝑛𝑔𝑒 𝑅𝑎𝑛𝑔𝑒 26100 26100
    According to H. G. Struges rule: Class interval (i) = = = = = 4419
    1+3.322𝑙𝑜𝑔𝑁 1+3.322𝑙𝑜𝑔30 1+3.322×1.477 5.907

    Hence, we consider class interval approximately 5000

    Requirement-1: An ordinary frequency distribution table

    Class Frequency
    10,000-15,000 3
    15,000-20,000 4
    20,000-25,000 5
    25,000-30,000 6
    30,000-35,000 9
    35,000-40,000 3
    Total 30

    Requirement-2: A relative frequency table


    Class Frequency Relative frequency {(frequency ÷
    Total frequency) × 100}
    10,000-15,000 3 10% [3÷30×100]
    15,000-20,000 4 13.33%
    20,000-25,000 5 16.67%
    25,000-30,000 6 20%
    30,000-35,000 9 30%
    35,000-40,000 3 10%
    Total 30 100% or 1
