Based off the three requirements that must be met before an analysis of variance test (ANOVA) can be used:

1. Samples must be randomly selected from the populations to be evaluated.

2. All populations from which the samples are selected must have a normal probability distribution.

3. All the populations from which samples are selected must have the same variance.

How might one know if the samples follow a normal distribution?
