## Bar Graph

A bar graph is a graphical representation of information.

Bars are used in bar graphs. Bar graphs can be created using vertical bars, horizontal bars, or grouped bars.

### Steps to Make a Bar Graph:

Step 1: Consider the title from the given data or tally chart.

Step 2: Choose a scale.

Step 3: Consider two axes, vertically and horizontally.

Step 4: Draw the bars according to the given data

Note:

A bar graph makes it easy to compare data.

#### Example of a Bar Graph:

Record the data in the form of a tally chart or information chart.

Choose a scale for each of the axis.

Now, draw a bar graph by using a scale and a data chart.

The horizontal axis shows the kinds of flowers; the vertical axis shows the number of flowers. Here, each grid line represents 2 units.

Example 1:

See the table of data and draw the bar graph.

The bar graph shows information about the number of pages read from a comic book by a group of friends.

Solution:

First, select the same title given to the table data.

The title of this bar graph is the ‘number of pages read.’

Next, we select a scale.

Each grid is equal to 5 units/5 pages.

We get the following bar graph.

Example 2:

Ashley had a fruit basket; he counted the fruits and made a tally chart. Draw the bar graph.

Solution:

First, select the same title given to the table data.

The title of this bar graph is the ‘Fruit Basket.’

Next, we select a scale.

Each grid is equal to 2 units/2 fruits.

We get the following bar graph:
