Definitions:

Independent Samples

Sets of data collected from distinct, non-overlapping populations.

Parametric Tests

Statistical tests that assume the underlying data distributions fit certain parameters, such as being normally distributed.

Errors In Assumptions

Mistakes or misjudgments made regarding the foundational conditions or premises upon which statistical analyses or models are based.

Nonparametric Techniques

Statistical methods that do not assume a specific distribution for the data and are often used for data that does not meet the assumptions necessary for parametric tests.
