👉 Histograms are graphical representations of data. They plot a bar graph that shows the frequency or distribution of numerical values in a set, such as the number of times each value appears. Each bar represents a certain amount of data, and if there is overlap between two bars (i.e., they have overlapping areas), it indicates how many numbers are contained within the same range. Histograms can be used for various purposes, including analysis of data, visualizing distributions, or comparing different groups or populations.
