## FAQs on RD Sharma Class 6 Maths Solutions Chapter 23 - Data Handling III (Bar Graphs)

**1. What is a bar graph?**

A bar graph is the statistical representation of data using bars. Bar Graphs are one of the easiest ways to explain sophisticated statistical information. Bar graphs are ideal for comparing discrete values of two or more objects of the same category. When a graph has a well defined zero point, we can easily understand the difference of the position of the positive and negative values. For the x-axis, the values to the right of the zero point are the positive values, and to the left of the zero point are the negative values. For the y-axis, the values above the zero point are the positive values, while values below the zero point are the negative values.

**2. What are the advantages and disadvantages of bar graphs?**

**The advantages of bar graphs are:**

Bar graphs help in assembling and interpreting a large set of data in simple, visual form.

Frequency distribution tables can easily be established in a pictorial form using bar graphs.

Readers can get an idea of the data at a glance.

Bar Graphs are more easily readable and easy to interpret, amongst other pictorial charts.

**The disadvantages of using bar graphs are:**

Sometimes, the data is so large that interpreting it using a bar graph becomes problematic.

Improper usage of legends and keys can give out wrong information.

Wrong scale information can change the value of the entire graph.

**3. What are the uses of bar graphs?**

Since bar graphs are so easy to use and read, they are used for a number of purposes. They are used to trace changes between categories, or over a period of time. Bar Graphs are the most suitable when the change over a period of time is big.

Bar Graphs are usually scaled and drawn in such a way that big data also fits on a small graph. Bar graphs help readers to understand large data easily and quickly.

**4. How to draw a Bar Graph?**

The steps to draw a Bar Graph are:

Deciding on the title of the Bar Graph.

Drawing both the axes and labelling them.

Noting down the data for both the axes.

Writing down the scale for both the axes.

Drawing the Bar Graph with respect to the categories.

These are just a few steps. For more elaboration, visit the Vedantu app or website. The study materials there shall guide the student to understand the topic and gain insights on it.
