## What are the uses of bar chart?

## How do you describe the shape of a bar graph?

The four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. A graph with a single peak is called unimodal. A single peak over the center is called bell-shaped. And, a graph with two peaks is called bimodal.

## What do you mean by bar chart?

A bar chart is a way of summarizing a set of categorical data (continuous data can be made categorical by auto-binning). The bar chart displays data using a number of bars, each representing a particular category.

## How do you describe a histogram?

A histogram is bell-shaped if it resembles a “bell” curve and has one single peak in the middle of the distribution. The most common real-life example of this type of distribution is the normal distribution.

## How do you explain a histogram?

A histogram shows how frequently a value falls into a particular bin. The height of each bar represents the number of values in the data set that fall within a particular bin. When the y-axis is labeled as “count” or “number”, the numbers along the y-axis tend to be discrete positive integers.
