What is Bar Chart? Histogram used for distribution of non-discrete variables while Bar Graph is used for comparison of discrete variables. In Histogram, we cannot rearrange the blocks while in Bar Charts, it is common to rearrange the blocks, from highest to lowest. Histogram used for displaying the frequency of occurrences and Bar Plots helps you to compare different categories of data. Report a Bug. Previous Prev. Next Continue. Home Testing Expand child menu Expand. Although histograms are made up of bars, they are not bar charts.
Make sure to edit the histogram if your software produces gaps between the bars. Histograms show distributions, bar charts compare categorical values. Next week we will discuss another chart form that is superior to histograms for comparing distributions and provides more information than bar charts do for comparing variables.
It includes the times visitors spent at a number of museum exhibitions. Other figures based on these data appear in Creating More Effective Graphs. This is a BETA experience.

And the distribution can be determined by a histogram. Also Read: Benefits of Data Visualization.
The histogram is used to showcase a graphical presentation that represents the data in the form of frequency; whereas a bar chart is also a graphical representation of data and the information that is used for the comparison of two categories.
Both bar charts and histograms are an important element of statistics. In simple terms, a bar chart is used in summarizing categorical data, where a histogram uses a bar of different heights, it is similar to the bar chart in many terms but the histogram groups the numbers into the ranges while representing the data. The difference between bar chart and histogram have been discussed above, which provide enough relevant information and understanding about the two, bar chart and histogram.
The main purpose of using a histogram is to organize and display a large set of information or numerical data in an intuitive and user-friendly way. Histograms will make it easy for the viewer to understand where too many variations were seen in the values. So, whenever you need to place your numerical data in a way that every viewer can understand easily, then you should make use of a histogram. Here are some of its applications: 1. Electoral data analysis 2. Weather forecast 3.
Disease tracking 4. Stocks trading 5. Business analysis 6. Histograms in photography Once you understand the purpose of histograms clearly, you will be able to use them in the right place for better understanding. A histogram is really useful for representing a huge amount of numerical data on graphs in an easy-to-understand manner. It allows you to compare different variables and categories easily.
You may also create double bar charts that allow you to evaluate two similar data sets at the same time. Some things you may communicate through a bar chart include:. Here's an example of when you might use a bar chart:. A high school teacher wants to compare how many of their students in each class period passed a recent exam to evaluate which period performed the best.
The x-axis would include categories for each class period, and the y-axis would designate the number of students in each class period who earned a passing grade.
If three students in the first-period class passed the exam, the bar would go up to the number three on the y-axis. Similarly, if nine students in the second-period class passed the exam, the bar would reach the number nine on the y-axis. A histogram is a type of bar graph used to display statistical or quantitative data. It allows you to show the frequency or distribution of continuous data and compare non-discrete values. Histograms include data ranges grouped into data bins or data intervals on the x-axis with values on the y-axis.
Some things you may communicate through a histogram include:. Here's an example of when you may use a histogram:. A high school teacher wants to evaluate a particular class period's performance on a recent exam. The x-axis includes score ranges in increments based on letter scores, such as 60—69 for students who earned a D and a catchall data bin for scores of 59 or less, and the y-axis would display the number of students who earned a grade in the specified range.
If six students earned C's, the bar for the 70—79 bin would reach six on the y-axis. Similarly, if 10 students earned B's, the bar for the 80—89 bin would reach 10 on the y-axis.

They may look similar since both graphs include two axes and bars to show value.
