A histogram is a graphical representation of the distribution of data. It is a type of bar graph that shows the frequency of occurrence of different values in a dataset. Histograms are used to visualize the shape of a distribution and to identify patterns and trends in the data.
Histograms are important because they can help us to understand the distribution of data and to make informed decisions. For example, a histogram can be used to determine the average value of a dataset, to identify the most common values, and to find outliers. Histograms can also be used to compare different datasets and to identify trends over time.
