Question

Draw a Histogram from the following data:
Marks 0-10 10-20 20-30 30-40 40-50 50-60
No. of students 5 6 8 6 5 4

Answer 1

Answer:

The minimum of the class widths of the data set is 10. So, we draw rectangles with class intervals as bases and the lengths of the rectangles given by

Length of Rectangle =

Classwidth

Frequency

×10.

Thus, the histogram can be drawn as follows.

Marks 0−10 10−20 20−40 40−50 50−60 60−70 70−90 90−100

No. of students 4 6 14 16 14 8 16 5

Class width 10 10 20 10 10 10 20 10
