Test Variable for Normality with a Q-Q Plot (Quantile-Quantilte Plot) in Excel

This video demonstrates how to create and interpret a normal Q-Q plot (quantile-quantile plot) in Excel. A normal Q-Q plot is used to determine how well a variable fits the normal distribution. In this example, three variables (normally distributed, positively skewed, and negatively skewed) are tested with a Q-Q plot.
