7. Construct simple bar graph

 

The data given below shows the number of people living in a particular street who completed their graduation in the following degree:

 

 

Let's follow the steps and draw the bar graph for the given data.

 

Step 1: Draw two perpendicular lines one horizontally for the degrees like B. A., B. Com., B. E., B. Sc., and B. D. S. and the other will be vertically for the number of people studied.

 

Step 2: The horizontal line will take the degrees with equal spaces between them and the vertical line takes the number of people from \(0\) to \(40\) (as the maximum number is \(37\)).

 

Step 3: Mark signs of equal breadth for each class and leave equal or not less than half a breadth between two classes.

 

Step 4: Now mark the values (\(10\), \(28\), \(37\), \(23\) and \(2\)) of the given degrees B. A., B. Com., B. E., B. Sc., and B. D. S. and form the rectangular bars in it. Thus, we constructed a simple bar graph with one variable.

 

Step 5: Now write the title as 'Preferred graduation' and the axes label  becomes 'Degrees' along the \(x\)-axis and 'Number of people' along the \(y\)-axis.
