Checking model assumptions:
We can use a quantile-quantile plot or QQ plot for short (Normal plot and Half-Normal plot in the GenStat output). The plot shows the residuals versus expected values given a Normal distribution. If both correspond well, dots should be on a diagonal as the ones shown in the plot are.

There should be some sort of statistical test for if a sample is obviously non-normal. Two common ones are the Shapiro-Wilks test and the Anderson-Darling test.
