STATISTICA offers several nonparametric hypothesis tests that are very useful when assumptions of traditional statistical tests (such as t-tests and ANOVA) fail. These nonparametric tests do not make distributional assumptions such as normality of the data that other tests make. The one sample t-test from the Basic Statistics module tests the population mean against a hypothesized value. This test assumes a normal distribution of the data. If this assumption is not met, a nonparametric test can be used. The Nonparametric module does not offer a specific one-sample test. This example illustrates how the one-sample nonparametric test...
