In statistics, histograms are used to graph the probability distribution of the data. Analysts and statisticians use them to analyze patterns of frequency, and visualize a numerical breakdown of what is being collected in the data. Histograms are useful for analyzing numerical data sets. However, not all histograms need to use a time period as the given range. This histogram shows the frequency of visitors to a restaurant in one hour bins within the range of a time frame. You’ve probably seen a histogram searching for the best time to visit a restaurant on Google! Histograms are graphs and are one way to visualize frequency distributions. A frequency distribution is the display of how often something occurred in a graph, table, or diagram. These bars are called bins or buckets, and together they represent what is called a frequency distribution. While histograms look like bar charts, they are different in that each bar is an interval of values of a metric.
