Difference Between a Histogram and a Bar Graph

Difference Between a Histogram and a Bar Graph, The Bar graph is a graphical representation of data that uses bars to compare different categories of data, whereas the Histogram is a graphical representation of data that uses bars to exhibit data by way of bars to illustrate the frequency of numerical data.

The distribution of non-discrete variables is represented by a histogram, but the comparison of discrete variables is represented by a bar graph.

While it is not possible to rearrange the blocks in a histogram, doing so in a bar chart is normal practice.

Bar plots and the histogram used to represent the frequency of occurrences allow you to compare various data categories.

The histogram is what?

A histogram is a sort of bar chart that shows the frequency distribution of continuous data by using bars to represent statistical information.

It displays the number of observations that fall inside the class or bin of values, also known as the range of values.

A histogram graphic uses vertical bars to depict the distribution of numerical data. A histogram graphic can be used to compare non-discrete values.

For instance, a histogram chart can be used to display the number of students that received English subject marks on a test in various ranges.

You must divide the observations into a logical sequence of intervals known as bins before creating a histogram.

A bar chart is what?

Using horizontal or vertical bars, a bar chart is used to compare the frequency, total count, sum, or average of data in several categories. Another name for it is a column chart.

You can compare different categories with the aid of a bar chart, which graphically represents the results.

The bar chart typically consists of an axis, label, scales, and bars that indicate quantifiable data like percentages or numbers.

All kinds of data, including quarterly sales, seasonal rainfall, and job development, are displayed using bar plots.

A double bar graph can occasionally be used to compare two data sets. It can also be used to quickly compare two or three data sets.

Benefits of a Histogram

Here are some advantages and pros of histograms:

You can use it to display a lot of data that is difficult to understand in tabular form.

It displays how frequently the various data values occur.

helpful for figuring out a process’s capacity.

You can use it to forecast how the process will perform in the future.

You may display the frequency of occurrences of data along with an interval using the histogram.

Benefits of Bar Diagrams

Here are some advantages and pros of bar graphs:

Whether the data is numerical or categorical, a bar graph can be used.

Each data type is shown in the bar graph as a frequency distribution.

It displays proportions or relative numbers for several categories.

A huge data set can be condensed visually.

Calculate important values quickly.

Show the outline of near numbers or proportions.

Large data sets in a graphic format make trends easier to understand than in tables.

The drawbacks of the histogram

These are the histogram’s disadvantages:

not allow you to read precise values due to data being categorized.

It simply utilizes continuous data.

It is difficult to compare two data sets in a histogram.

The Histogram’s use of intervals prohibits the determination of a precise measure of central tendency.

The drawbacks of a bar graph

The disadvantages of a bar graph are as follows:

Only the frequencies of the components of a data set are shown in a bar graph.

With a bar graph, more explanation is required.

Key presumptions, causes, effects, or patterns are not revealed.

Key Difference Between a Histogram and a Bar Graph

HistogramBar Graph
The term “histogram” describes a graphical depiction that uses bars to indicate data and the frequency of numerical data.The bar graph is a type of data visualization that employs bars to compare several data categories.
Distribution of non-discrete variables.Variables that are discrete are compared.
There are no spaces between the bars since they touch.There are spaces between the bars because they never contact.
In this kind of graph, the elements are clustered together to form ranges.In this type of graph, the members are viewed as separate entities.
Histogram width may vary.The bars in the graph are of equal width.
to show how frequently something happens.To compare different categories of data.
The data points in a histogram are categorized and displayed according to their bin values.Each data point is shown as a single bar in the bar graph.
The histogram’s items are numerical data that should be grouped to represent the data range.Items need to be regarded as distinct entities, unlike the bar graph.
We are unable to rearrange the blocks in a histogram.Blocks in a bar graph are frequently rearranged from highest to lowest.

  1. The difference is just continuous vs. categorical. 😉
