Solution - The following distribution gives the daily income of 50 workers of a factory - CBSE Class 10 - Mathematics

ConceptGraphical Representation of Cumulative Frequency Distribution

Question

The following distribution gives the daily income of 50 workers of a factory.

Daily income (in Rs 100 − 120 120 − 140 140 − 160 160 − 180 180 − 200
Number of workers 12 14 8 6 10

Convert the distribution above to a less than type cumulative frequency distribution, and draw its ogive.

Solution

The frequency distribution table of less than type is as follows

Daily income (in Rs)

(upper class limits)

Cumulative frequency
Less than 120 12
Less than 140 12 + 14 = 26
Less than 160 26 + 8 = 34
Less than 180 34 + 6 = 40
Less than 200 40 + 10 = 50

Taking upper class limits of class intervals on x-axis and their respective frequencies on y-axis, its ogive can be drawn as follows.

Is there an error in this question or solution?
