What is histogram?
Histogram: A chart showing how the values of one numeric variable are distributed: the range is cut into equal-width bins and the height of each bar counts the values falling in that bin. It reveals shape, spread, skew and outliers, and the number of bins changes how it looks.
Histogram: an example
A histogram of 2,000 delivery times in 5-minute bins may show most between 20 and 40 minutes with a long tail beyond 60.
