Definitions:

Generalizability

The extent to which findings from a study can be applied to larger populations or different contexts.

Sampling Error

The difference between a sample statistic and its corresponding population parameter, arising purely by chance because a sample is only part of the whole.

Sample Approximates

Estimates derived from a sample that are used to infer characteristics of the overall population.

Research Hypotheses

Statements made by researchers that predict a relationship or difference between variables in a study.
