3

What are potential reasons for the failure to reject a null hypothesis?

1. Type II error (chance)
2. Low power
3. Poor experimental methods
4. Unreliable variables
5. Violated assumptions
6. Incorrect formulation of theoretical implications
7. Misspecification of expected outcome

4

What are threats to hypothesis validity?

1. Inconsequential research hypothesis
2. Ambiguous research hypothesis
3. Non-congruence of research hypothesis and statistical hypothesis
4. Diffuse statistical hypotheses and tests
