... What we have done so far is useful, but not useful enough! If we think about it, we will see that the estimate of the population mean (i.e. all the measurements that we ever could make of the same type - the diameter of this type of cell, etc.) has been fixed by the sample of four individuals. If we ...

... several groups. However, that test only tells us when differences exist, not which specific groups differ. The goal of this section is to adapt the inference procedures of section 13.1 to use the results of the ANOVA analysis. This will allow us to find a confidence interval for the mean of any grou ...
