The axes in a double bar graph are two. A double bar graph's x-axis displays the comparison categories, and the y-axis shows the scale.

6. What topics are covered in class 7 maths chapter 3 exercise 3.3 solutions?

Exercise 3.3 focuses on data handling, specifically on interpreting data using bar graphs and pictographs.

7. How do you interpret data presented in bar graphs in class 7 maths exercise 3.3?

To interpret data in bar graphs, observe the height of the bars to understand the frequency or quantity represented for each category.

8. What is the purpose of using pictographs in class 7 maths ex 3.3?

Pictographs help in representing data visually using pictures or symbols to make it easier to understand and interpret.

9. Can you explain how to draw a bar graph for the data given in Exercise 3.3?

Sure, to draw a bar graph, first, label the categories on the horizontal axis and the corresponding frequencies or quantities on the vertical axis. Then, draw bars for each category with heights proportional to the data values.

10. How do you compare data using bar graphs and pictographs in Exercise 3.3?

In bar graphs, compare the heights of bars directly, while in pictographs, compare the number of pictures or symbols used to represent each category.
