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 :

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 |
