The widths 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 .
CLASS            FREQUENCY
>20                         50
>30                         44
>40                         28
>50                        20
​>60                        15

Dear Student,

The grouped frequency distribution table is shown below :

 
Width (in mm)  Cumulative frequency Class interval Frequency
≥ 20 50 20−30 50−44 = 6
≥ 30 44 30−40 44−28 = 16
≥ 40 28 40−50 28−20 = 6

≥ 50
20 50−60 20−15 = 5
≥ 60 15 60−70 15−7 = 8

≥70
7 70−80
7−0 = 7
≥ 80 0    


Regards
