Hypothesis tests for the means are hypothesis tests used to test the means of samples in order to make inferences about the means of the populations from which they are drawn.
Parametric tests (tests that rely on the data conforming to a normal distribution) include:
||comparing the mean against a specified value using a sample of 30 items or fewer
|Two sample t-test
||comparing the means of two samples of 30 items or fewer
||comparing the means of two samples of 30 items or fewer, when the items in the two samples can be 'paired'
||comparing the the mean against a specified value when the sample has more than 30 items or the standard deviation is known
Nonparametric tests for the mean include:
If there are more than two populations the Analysis of Variance (ANOVA) is used.
