# Histogram vs. Bar Graph: What's the Difference?

Edited by Sumera Saeed || By Sara Rehman || Published on November 27, 2023

**A histogram is a graphical representation of data distribution using contiguous bars, while a bar graph displays categorical data with separate bars.**

## Key Differences

Histograms are used to show the distribution of a numerical dataset, indicating the frequency of data within certain ranges. Bar graphs, in contrast, represent categorical data, with each bar representing a different category.

In a histogram, bars are adjacent, touching each other to indicate continuous data ranges. Meanwhile, in a bar graph, bars are separate, emphasizing the distinctiveness of each category.

Histograms often deal with large data sets and are useful in statistical analysis, showing trends over a range of values. While, bar graphs are more suited for comparing discrete quantities or categories, such as survey results.

The height of bars in a histogram reflects the frequency of data in each interval. However, in a bar graph, the height or length of each bar corresponds to the value or count of the category it represents.

Histograms are typically used for data like measurements or intervals, where the data falls into natural ranges. Whereas, bar graphs are used for data that can be divided into separate categories, like brands, types, or groups.
