Question

Draw a histogram to represent the following frequency distribution.
Class - Interval
10 - 19
20 - 29
30 - 39
40 - 49
50 - 59

Frequency
7
10
20
5
15

Answer 1

1 ) If the class intervals given are inclusive

( limits ) convert them into the exclusive

form ( boundaries ) since the histogram

has to be drawn for a continuous series .



2 ) Choose a suitable scale on the

x - axis and mark the class intervals

on it .

3 ) Choose a suitable scale on the

y - axis and mark the frequencies on

it .

Scale : x - axis 1cm = 10 units

( one class interval )

y - axis 1 cm = 2 units

4 ) Draw rectangles with class intervals

as bases and the corresponding

frequencies as the corresponding heights.
