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
- 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.
- 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.
