2.17: Introduction to Histograms


What you’ll learn to do: Describe the distribution of quantitative data using a histogram.

When presented with large data sets, the dotplot is sometimes cumbersome to put together. In addition, it may not be the cleanest way to present the data. For large datasets, a histogram can represent the numerous data points more simply as bars instead of an immense amount of data points in a dotplot. Similar to the dotplot, a histogram is useful in displaying the distribution (aka shape) of the data.
