Residual plot (residuals versus predicted values) is not a suitable plot to check the normal distribution of data within each group. It is used to assess the linearity, homoscedasticity, and independence assumptions of a linear regression model. B. The normal probability plot of the residuals is a graphical method that allows us to check ...
WebbThe assumption of homoscedasticity was verified with the Levene test, and normality was evaluated with the normal probability plot of the residuals for each ANOVA. When these assumptions were not fulfilled, data transformation was applied. WebbPlots for examining residuals Any graph suitable for displaying the distribution of a set of data is suitable for judging the normality of the distribution of a group of residuals. The …
