What is the difference between a bar graph and a histogram?
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.
Answer: The basic differences between a bar graph and a histogram are given in the solution.
Let's understand the difference between a bar graph and a histogram.
- 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:
|Equal space between every two consecutive bars.||No space between two consecutive bars. They should be attached to each other.|
|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:
