Question

The following data contains the amount of rent paid every month for 24 students from a statistics course.

Make a relative frequency distribution using 7 classes. Also draw Histogram and ogive curve for the same.

Data of Monthly Rent: 1500, 1350, 350, 1200, 850, 900, 1500, 1150, 1500, 900, 1400, 1100, 1250, 600, 610, 960, 890, 1325, 900, 800, 2550, 495, 1200, 690

Answer 1

No. of students = 24

So relative frequency of a class = Frequency of the class / 24

Relative Frequency Distribution :-

Class Boundaries	Tally Marks	Frequency	Relative Frequency
350-550	||	2	2/24=0.08333
550-750	|||	3	3/24=0.125
750-950	||||||	6	6/24=0.25
950-1150	||	2	2/24=0.08333
1150-1350	||||	5	5/24=0.20833
1350-1550	||||||	5	5/24=0.20833
>1550	|	1	1/24=0.04167

Class Boundaries	Relative Frequency	Cumulative Frequency (less than type)
300-500	0.08333	0.08333
500-700	0.125	0.20833
700-900	0.25	0.45833
