## What is the importance of bar graph?

A bar diagram makes it easy to compare sets of data between different groups at a glance.

The graph represents categories on one axis and a discrete value in the other.

The goal is to show the relationship between the two axes.

Bar charts can also show big changes in data over time..

## What is bar diagram and its types?

A bar graph can be defined as a chart or a graphical representation of data, quantities or numbers using bars or strips. Bar graphs are used to compare and contrast numbers, frequencies or other measures of distinct categories of data.

## Where do you use a bar graph?

Bar graphs are used to compare things between different groups or to track changes over time. However, when trying to measure change over time, bar graphs are best when the changes are larger.

## How is a bar chart different from a histogram?

A bar graph breaks categorical data down by group, and represents these amounts by using bars of different lengths. It uses either the number of individuals in each group (also called the frequency) or the percentage in each group (called the relative frequency).

## What are different types of graph?
