# 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.
