In this article,we will share All About Histogram: Meaning, Construction, And Types.By using the height of joined rectangular bars to indicate the corresponding frequencies in the class intervals, a histogram represents the grouped frequency distribution with continuous class limits in statistics. We will explore the basic concept of a histogram, what it is, how it is constructed, and what types of histogram there are.

## What is Histogram?

The histogram is a graphic representation of a frequency distribution grouped into continuous classes. The diagram shows a series of rectangles with bases and the distances between class boundaries. All plotted rectangular bars are adjacent to each other, and the height of the rectangular bar is equal to the frequencies of similar as well as different classes.

## How to draw a Histogram?

The steps for drawing a histogram are as follows:

First, it is important to decide the title of the graph based on the category of the given data set when drawing the histogram.

It is then necessary to draw two axes-a horizontal axis (x-axis) and a vertical axis (y-axis), and to mark the class intervals (x-axis) and frequencies (y-axis).

Using the values from the data set, step 3 is to determine the range of the scale. Both axes should have the same scale range.

The last step is to draw rectangular bars on the horizontal axis (x-axis) with the bases equal to the class intervals and the heights equal to the corresponding frequencies. At this point, you can check the beacon’s construction.

Consider the following points when constructing a histogram:

- In determining the title for a particular set of data, make sure it is short and descriptive.
- Whenever possible, convert inclusive intervals into exclusive intervals.
- Make sure to draw the rectangular bars on the x-axis and the y-axis for each class interval. Class boundaries are marked on the x-axis and frequencies are marked on the y-axis.
- In the case of equal intervals, the length of each rectangular bar should match the corresponding frequency of the corresponding class.
- If the intervals are not equal, then the areas of the rectangular bars equal the respective class frequencies.

## What are the types of Histograms?

Based on the frequency distribution of the given data, the histogram is classified into various types such as normal distribution, bimodal distribution, multimodal distribution, skewed distribution, edge peak distribution, and so on. Here are some examples of histogram types:

**Histograms with normal distribution are also known as bell-shaped histograms.**As a result, the histogram is known as a bell-shaped histogram since it only has one peak.

- Uniform Histogram: A height of the plotted rectangular bars on the graph is more or less the same in the uniform histogram. It might involve distribution having several peaks.

- Bimodal Histogram: A histogram with two peaks is called a bimodal histogram. Two kinds of observations are combined in one set of data to form bimodality.
- By using the height of joined rectangular bars to indicate the corresponding frequencies in the class intervals, a histogram represents the grouped frequency distribution with continuous class limits in statistics. We will explore the basic concept of a histogram, what it is, how it is constructed, and what types of histogram there are.
**Hetogram skewed: A skewed histogram is also known as an asymmetric histogram.**If, after dividing the histogram into two identical halves, the two halves are not similar in shape and size, then the graph will be called a skewed histogram. Right-skewed histograms and left-skewed histograms are two types of skewed histograms.
