Study Notes

Internal Validity

Internal validity refers to a research design's ability to adequately test its hypotheses.
Example of internal validity: using radio buttons instead of drop-down menus for respondents to indicate their responses.

- Enables quick changeover from one activity to another.
- Requires setup, which includes some kind of changeover.
