What is a Histogram?
Histograms show the spread, or dispersion, of variable data. The customer's upper specification (USL) and lower specification limits (LSL) determine how well the process delivers on customer requirements. Measurements outside of the spec limits represent data points that don't meet customer requirements.

I am very impressed with QI Macros Software. I work with Excel eight hours a day and thought that I had written macros that made me efficient.
