It also may be mistaken with a bar chart because it looks pretty similar. However, there are distinct differences between them as histograms are dedicated to showing distributions of variables, while bar charts compare variables.
HistogramBar GraphIn a histogram, data is grouped into continuous number ranges, and each range corresponds to a vertical bar.Using a bar graph, we can present categorical data in the form of rectangular bars, where the length of each one is proportional to the value they stand for.
There are two consecutive bars, and the x-axis should represent only continuous data in terms of numbers.There must be equal space in a bar graph between every two following bars, and the x-axis can represent anything.
