Articulate assumptions for multiple linear regression 2. Also would be good to report the P values for the predictors, because I think you are only reporting their beta values without corresponding P values. 9% of the variation in Total is explained by this model. table function that works similarily but creates bootstrap confidence intervals). The fit of a proposed regression model should therefore be better than the fit of the mean model. The simplest of them all is the 22 or 2 x 2 experiment. Also, you can use as guide. General; There was a statistically significant difference between groups as determined by one-way ANOVA (F(2,27) = 4. In such cases, we resort to Factorial ANOVA which not only helps us to study the effect of two or more factors but also gives information about their dependence or independence in the same experiment.
