Definitions:

Nonparametric Tests

Statistical tests that do not assume a specific distribution of the data, often used when data doesn't meet assumptions necessary for parametric testing.

Normally Distributed

Describes a dataset whose distribution forms a symmetrical bell-shaped curve when plotted, characterized by data clustering around a mean.

Dependent Variable

Variable measured by the researcher.

Nominal Measurement

A measurement scale used to categorize data without implying any order or numerical value among the categories.
