What is the difference between a bar graph and a histogram?
Solution:
The fundamental difference between histograms and bar graphs from a visual aspect is that the bars in a bar graph are not adjacent to each other.
- A bar graph is the graphical representation of categorical data using rectangular bars where the length of each bar is proportional to the value they represent.
- A histogram is the graphical representation of data where data is grouped into continuous number ranges and each range corresponds to a vertical bar.
The main differences between a bar chart and a histogram are as follows:
| Bar Graph | Histogram |
|---|---|
| Bar graph represents categorical data. | Histogram represents numerical data (discrete or continuous data). |
| Equal space between every two consecutive bars. | No space between two consecutive bars. They should be attached to each other. |
| Data can be arranged in any order. | Data is arranged in the order of range. |
| The x-axis can represent anything. | The x-axis should represent only continuous data that is in terms of numbers. |
However, in both the graphs, the y-axis represents numbers only. We can understand these differences from the following figure:
Thus, we have seen the basic differences between a bar graph and a histogram.
What is the difference between a bar graph and a histogram?
Summary:
The basic difference between a bar graph and a histogram is that a bar graph is used to represent categorical data whereas a histogram is used to represent numerical data.
