For example, the count of students who got English subject marks on an exam in various ranges that can be visualized using a histogram chart. Bar Plots are used to display all types of data, from quarterly sales, seasonal rainfall to job growth. Sometimes you can use a double bar graph to evaluate two data sets. It is also used to evaluate two or three data sets easily. With the help of Bar Chart, you can also do various types of category comparison, which is graphically visualized using a bar chart. Generally, the bar chart will have an axis, label, scales, and bars, represent measurable values like percentages or numbers.
Example of Histogram
While constructing a Histogram, you need to take the observations and split them into a logical series of intervals called bins.
Above given chart showing the GDP rate range in a special year.
Example of Bar Chart
Here is a survey of 100 people about their favorite food Bar Graph:
The above-given example shows the most liked food is Sandwich, and the least liked food is pasta in this survey.
Difference Between Histogram and Bar Chart
Advantages of Histogram
Here are the Pros/benefits of histogram:
It helps you to display a large amount of data, which is hard to interpret in a tabular form. It shows the frequency of occurrences of the different data values. Useful when calculating the capability of a process. It helps you to predict the future performance of the process. The histogram allows you to show the frequency of occurrences of data along with an interval.
Advantages of Bar Graphs
Here are the Pros/benefits of bar graph:
You can use a bar graph with numerical or categorical data. The bar graph displays each data category in a frequency distribution. It shows relative numbers or proportions of multiple categories You can summarize a large data set in visual form. Estimate key values at a glance. Display close numbers or proportions outline. Large data set in the visual form helps you to clarify trends better than tables.
Disadvantages of Histogram
Here are the cons/drawback of histogram:
Not allow you to read exact values because data is grouped into categories. It uses only with continuous data. In Histogram, it is not easy to compare two data sets. The use of intervals in the Histogram prevents the calculation of an exact measure of central tendency.
Disadvantages of Bar Graph
Here are the cons/drawback of a bar graph:
A bar graph displays only the frequencies of the elements of a data set. You need additional explanation with Bar graph. It fails to reveal key assumptions, causes, effects, or patterns.
