Answers
Answer:
We can draw the bar graph by following these steps:
Step 1. On a graph paper, draw a horizontal line OX and a vertical line OY. These two lines represents the x-axis and the y-axis respectively.
Step 2. Along OX, write the names of the sports at points taken at uniform gaps.
Step 3. Choose the scale: 1 small division = 1 student
1 big division = 10 students
Step 4. Then, the heights of the various bars are:
Cricket = 7 big divisions and then 5 small divisions = 75 small divisions
Football = 3 big divisions and then 5 small divisions = 35 small divisions
Tennis = 5 big divisions = 50 small divisions
Badminton = 2 big divisions and then 5 small divisions = 25 small divisions
Swimming = 6 big divisions and then 5 small divisions = 65 small divisions
Step 5. On the x-axis, draw bars of equal width and heights obtained in step 4 at the points marked in step 2
