The histogram refers to a graphical representation that shows data by way of bars to display the frequency of numerical data whereas the bar graph is a graphical representation of data that uses bars to compare different categories of data.

Now let's think about different sets of data and which would be better a histogram or a bar graph. The probability of each event is represented by the height of one bar. Histogram refers to a graphical representation;

A histogram is a type of bar chart that displays the frequency distribution of continuous data.

The histogram looks more similar to the bar graph, but there is a difference between them. Since a discrete distribution is completely specified by the probabilities of each of its events, we can represent it by a bar graph. In other words, it provides a visual interpretation of numerical data by showing the number of data points that fall within a specified range of values (called bins). Histograms are based on area, not height of bars.
