Determining Normal Distribution Using the Empirical Rule

This lesson explains how to determine if a distribution is normal using the empirical rule. It reviews the concepts of mean and standard deviation, differentiates between continuous and discrete distributions, and outlines the conditions for using a normal distribution model. Practical examples are provided to illustrate the application of the empirical rule.
