Question

Construct a frequency table for the following marks obtained by 50 students using equal intervals taking 16-24 (24 not included) as one of the class intervals. Also draw a histogram for the data. 52,16,18,20,42,48,39,38,54,58,47,37,25,16,24,49,36,35,53,21,30,43,56,34,33,17,22,24,37,41,40,50,54,56,54,36,38,42,44,56,17,18,22,24,17,18,58,23,29,58

Answer 1

Step-by-step explanation:

Total number of values

=

50

Range

=

Highest value

−

Lowest value

=

98−

8=

90

Let us divide the given data into

10

classes.

∴

Length of the Class interval

=

Number of class interval

Range

=

1 0

9 0

=

10

The frequency table of the marks obtained by

50

students in a mathematics test is as follows.
