A bar graph is a tool used to organise data for various decision making purposes. The data that is used in bar graphs is discrete in nature. It is a representation of frequency and therefore, the larger the frequency, the higher the bar graph. This type of graph provides an accurate visual representation of various data to make it easier to understand.

A histogram is a kind of bar graph that shows numbers that are represented by groups. It gives a great look into the variation in frequency and is a pertinent tool for decision making. The graph is based on bars that represent various numbers. Many companies use histograms to get a visual understanding of large amounts of data.
