A probability distribution is a statistical concept that enables us to estimate the chance of a particular value occurring over a range of values. This module introduces this topic, using Minitab software to help visualize the normal distribution and some common patterns associated with non-normal data such as natural limits, artificial limits, multiple modes and mixtures. For practitioners, a working knowledge of probability distributions helps guide your day-to-day process improvement. (This is the first in a set of three lectures on Common Probability Distributions.)
