# Histograms VS. Bar Charts

Learn the differences between histograms and bar charts. Make histograms and bar charts easily, quickly and flexibly.

### Definition of Histograms and Bar Charts

Bar charts and histograms can both be used to compare the sizes of different groups. A Bar chart is made up of bars plotted on a graph.

Histogram is a chart representing a frequency distribution; heights of the bars represent observed frequencies. In other words a histogram is a graphical display of data using bars of different heights. Usually, there is no space between adjacent Bars.

From the definition we can see their common point: The height of the column indicates the size of the group defined by the column label.

### Difference between Histograms and Bar Charts

**Bar Chart**

- The columns are positioned over a label that represents a categorical variable.
- The height of the column indicates the size of the group defined by the categories.

**Histogram**

- The columns are positioned over a label that represents a quantitative variable.
- The column label can be a single value or a range of values.

Here is the main difference between them. With bar charts, each column represents a group defined by a categorical variable; and with histograms, each column represents a group defined by a quantitative variable.

One indication of this distinction: it is always appropriate to talk about the skewness of a histogram; that is, the tendency of the observations to fall more on the low end or the high end of the X axis.

Differently, bar charts' X axis does not have a low end or a high end; because the labels on the X axis are categorical - not quantitative. Therefore, it is less appropriate to comment on the skewness of a bar chart. Refer to the following diagram to see a visual comparison between them.

### Why Use Histograms and Bar Charts

- Ease data analysis.
- Simplify complicated statistics and ideas.
- Add interest and fun to presentation (reports, essays and so on).
- Make presentation more compelling and comprehensible.
