Nonparametric tests are often based on rankings rather than on specific numerical values, making them appropriate for data that cannot be assumed to follow a normal distribution or for smaller sample sizes. Nonparametric tests do not necessarily have greater power or increase the probability of rejecting the null hypothesis, and they can be used with various types of data, not just interval or ratio data.
