Six points have these coordinates: The normal probability plot and the residuals versus fitted values plots generated by Minitab are shown below. Does it appear that any regression assumptions have been violated?

Regression Assumptions

Fundamental conditions that must be met for the results of a regression analysis to be valid, including linearity, independence of errors, homoscedasticity, and normality of residuals.

Normal Probability Plot

A graphical technique for assessing whether or not a data set is approximately normally distributed, plotting observed values against normally distributed scores.

Residuals Versus Fitted Values

A method to visualize the difference between observed values and those predicted by a model, useful in diagnosing model fit.
