https://doi.org/10.34157/978-3-648-16937-7 now describe the test for the case of more than two samples (Note: applying the . test to the difference between largest and smallest mean will give the wrong answer). This test is based on the fact that the mean of a sample of size . from a normal population with given ., is itself normally distri

https://doi.org/10.1007/978-3-8349-9076-1 are often called ‘parameters’ of the normal distribution. In general, if the values of certain properties of a theoretical distribution (e.g. its mean, variance, 3rd moment, etc.) are known and if the distribution is then completely specified (i.e. if its frequency curve can be plotted) these prope

The problem then is to find
