Abstract: Abstract This is an introduction to the two key tools for statistical inference. Confidence intervals on a population mean are introduced. This is followed by an introduction to the ideas behind hypothesis testing. They are applied to test a population mean. Since these procedures can depend, in the case of small samples, on the population distribution being normal, tests of this assumption are discussed. When the usual tests cannot be used, the Wilcoxon signed ranks test is introduced. This is followed by a discussion of statistical power and the difference between clinical significance and statistical significance.
