Question 40 The following distribution gives the daily income of 50 workers of a factory Convert this distribution to less than type of cumulative frequency distribution and draw its ogive.
First we find cumulative frequency
and then we convert it into a less than type ogive
Daily income Number of
workers
400 – 420 12
420 – 440 14
440 – 460 8
460 – 480 6
480 – 500 10
Cumulative frequency
12
12 + 14 = 26
26 + 8 = 34
34 + 6 = 40
40 + 10 = 50
Daily income
Less than 420 - 12
Less than 440 - 26
Less than 460 - 34
Less than 480 - 40
Less than 500 - 50
