I put it into buckets that A histogram is a chart that plots the distribution of a numeric variable's values as a series of bars. How big are each of those? Available online at, Food Security Statistics. Food and Agriculture Organization of the United Nations. After choosing the appropriate ranges, begin plotting the data points. The five numbers used to create a box-and-whisker plot are: The following graph shows the box-and-whisker plot.
