A normal probability plot is a type of residual plot that can be used to check the normality assumption of the multiple regression model. A normal probability plot plots the residuals against a theoretical normal distribution. If the residuals are normally distributed, then the points on the plot should follow a straight, diagonal line. If the points on the plot deviate significantly from a straight line, it may indicate that the normality assumption of the multiple regression model is not met.
