Question 3
Draw a histogram of the following distribution.

$\begin{array}{cc}\text{Height(in cm)}& \text{Number of students}\\ 150-153& 7\\ 153-156& 8\\ 156-159& 14\\ 159-162& 10\\ 162-165& 6\\ 165-168& 5\\ \text{Total}& 145\end{array}$

Answer 1

Clearly, the given frequency distribution is in the exclusive form.
Along the horizontal axis, we represent the class intervals of heights on some suitable scale. The corresponding frequencies of the number of students are represented along the vertical axis on a suitable scale.
The given intervals start with 150 - 153 It means that there is some break $(\approx )$ is indicated near the origin to signify the graph is drawn with a scale beginning at 150.
A histogram of the given distribution is given below.
