Construct a frequency distribution table for the data above
Solution:
Given, the data represents the cumulative frequency of marks of 800 students in an examination.
We have to construct a frequency distribution table for the data.
Marks |
Cumulative frequency |
Class interval |
Frequency |
Below 10 |

Below 20 |
50 |
10 - 20 |
50 - 10 = 40 |
Below 30 |
130 |
20 - 30 |
130 - 50 = 80 |
Below 40 |
270 |
30 - 40 |
270 - 130 = 140 |
Below 50 |
440 |
40 - 50 |
440 - 270 = 170 |
Below 60 |
570 |
50 - 60 |
570 - 440 = 130 |
Below 70 |
670 |
60 - 70 |
670 - 570 = 100 |
Below 80 |
740 |
70 - 80 |
740 - 670 = 70 |
Below 90 |
780 |
80 - 90 |
780 - 740 = 40 |
Below 100 |
800 |
90 - 100 |
800 - 780 = 20 |
