If there are not enough observations in each group to check normality, you may want to examine the residuals (each observation minus the mean of its group). On the other hand, for "residual normality", Wikipedia is on board with it: Since it is a non-parametric method, the ...
I have a question regarding how concerned I should be regarding a potential violation from the normality of residuals assumption in a linear mixed model. I have a relatively small data set, and after fitting the model (using 'lmer' in R), a Shapiro-Wilks test reveals a significant d...

Looking at the histogram of both the Achieve response variable and of the residuals, it can be seen that they are both of a right skewed distribution. To reduce the right skewness present, the logarithm of the response variable Achieve could be taken to transform it. ...

The type of non-normality and the type of test is important here. Also, if you are using an ANOVA or regression model, the important thing is the normality of the residuals not the normality of the raw data. It also depends how risk averse you are. Some people immediately flee for the...
If there are not enough observations in each group to check normality, you may want to examine the residuals (each observation minus the mean of its group). To do this, open a separate spreadsheet and put the numbers from each group in a separate column. Then create columns with the mean...
