Question

the width of 50 leaves of a plant were measured in mm and their cumulative frequency distribution is shown in the following table. make frequency distribution table for this width (in MM) 20 ,00, 40,50,60,70,80 cumulative frequency 1 6 15 20 28 44 50​

Answer 1

Given cumulative frequency table 'or more' type of table.

So, we first write the intervals and find their respective frequency by subtracting the cumulative frequency of next interval from cumulative frequency of particular interval

For example frequency of interval 20 -30 = 50-44=6

frequency of 30-40 =44-28=16

and so on

Doing that ,we get the following table
