Parametric tests usually have stricter requirements than nonparametric tests, and are able to make stronger inferences from the data. They can only be conducted with data that adheres to the common assumptions of statistical tests. The most common types of parametric test include regression tests, comparison … See more Statistical tests work by calculating a test statistic – a number that describes how much the relationship between variables in your test differs from … See more You can perform statistical tests on data that have been collected in a statistically valid manner – either through an experiment, or through observations made using probability … See more This flowchart helps you choose among parametric tests. For nonparametric alternatives, check the table above. See more Non-parametric tests don’t make as many assumptions about the data, and are useful when one or more of the common statistical assumptions are violated. However, the … See more WebThe first step is to state the null hypothesis and an alternative hypothesis. Null hypothesis: μ 1 - μ 2 = 0. Alternative hypothesis: μ 1 - μ 2 ≠ 0. Note that these hypotheses constitute a two-tailed test. The null hypothesis will be rejected if the difference between sample means is too big or if it is too small.
