Histogram: When is it used?

Histograms illustrate the process distribution and are used to make predictions about a stable process. If the system is unstable, the histogram will have little predictive value.

Use histograms when you can answer yes to these questions:

1. Do you have a data set of related values?

2. Do you need to visualize the central location, spread, and shape of the data?
