Following is the distribution of marks of 70 students in a periodical test: Marks Less than 10 Less than 20 Less than 30 Less than 40 Less than 50 Number of students 3 11 28 48 70 Draw a cumulative frequency curve for the above data.

Philoid · Accepted Answer

The frequency distribution table for ‘less than’ type is:

MARKS	CUMULATIVE FREQUENCY (C_f)
Less than 10	3
Less than 20	11
Less than 30	28
Less than 40	48
Less than 50	70

Lets plot a graph of ‘less than ogive’, taking upper limits of the class intervals on x - axis and cumulative frequencies on y - axis.
