**Construction of a bar graph :
Steps : **

1. On the graph paper draw a horizontal line (x-axis) and a vertical line (y-axis)

2. Along the horizontal line, mark points at equal distances and write the names of the items for which the data is to be represented.

3. Choose a suitable scale which shall determine the height of the bars.

4. Locate the heights of different bars according to scale.

5. On x-axis draw bars of equal width according to the required height.

6. Keep the distance between the bars the same.

Drawing a bar graph : Let us draw a bar graph for this data.

First of all draw a horizontal line and a vertical line. On the horizontal line we will draw bars representing each fruit and on vertical line we will write numerals representing number of students.

Let us choose a scale. It means we first decide how many students will be represented by unit length of a bar.

Here, we take 1 unit length to represent 1 student only. We get a bar graph as shown in adjoining figure.

Ex. 4 : Read the bar graph given below and answer the following questions.

(i) What is the total number of students in all the clubs together ?

Sol. 20 + 30 +40 + 20 = 110 students

(ii) Which club has more students and how many ?

Sol. Drama club, 40 students

(iii) Which club have equal number of students ?

Sol. Cricket club and music club

(iv) How any students are there in hockey club ?

Sol. 30 students.

(v) What information is given in the bar graph ?

Sol. The bar graph represetns the number of members of different sports clubs.
