Summarise probability distributions
Calculate P values from the normal distribution, corresponding to specified test statistic and mean and standard deviation. Also calculates critical values for the same normal distribution corresponding to the specified alpha (significance) level. Default values of 0 for distribution mean and 1 for standard deviation correspond to the standardised normal (Z) distribution.
Inputs are the test statistic, mean and standard deviation for the distribution and the specified alpha for calculation of critical values.
The program outputs 1 and 2-tailed P values, 1 and 2-tailed critical values and the probabilities associated with values greater than or less than the observed test value, as well as a summary and plot of the distribution.
