Normal Distribution

Symmetric bell-shaped probability distribution defined by its mean and standard deviation.

Examples

01The fill weights of 500 g bags follow a normal distribution with a mean of 503 g and a standard deviation of 1.2 g.
02Before calculating capability in Measure, the Green Belt runs a normality test and plots a histogram to confirm a normal distribution.
03When the data turns out not to follow a normal distribution because of a hard lower stop, the team uses a non-normal capability method and records why.
