Things I still need to know.

Question 1

Explain the difference between Reliability and Validity

Answer 1

Reliability is consistent scores,
Validity assess whether the scores are sufficient for
Statistical Conclusion Validity (correlation exists?)
Internal Validity (Cause & Effect Relationship?)
Construct Validity (can generalize from items to construct)
External Validity (can generalize to other ppl, places, times.

Question 2

What are 3 threats to Statistical Conclusion Validity?

Answer 2

PMR

Power - correct by increase sample size
Measurement Error - correct by using multiple measures
Range Restriction - correct by stronger manipulation, wider sample

Question 3

4 types of reliability

Answer 3

Inter-Rater
Test-Rest
Parrellel Forms
Internal Consistency

Question 4

The different types of Construct Validity

Answer 4

Translation Validty
- Face Validity
- Content Validity
Criterion Validity
- Predictive Validity
- Concurrent Validity
- Convergent Validity 
- Discriminant Validity

Question 5

The 8 threats to Construct Validity

Answer 5

MIMIDUCT

Mono-Operation bias - IV: setting up the experiment 1 way
Mono-Method bias - DV - measuring the DV only 1 way
Interaction of Test - people under test get more treatment effect
Iteraction of other Treatments
D -definition is poor
U - Unintended consequence of the treatement (side effects)
Construct Levels are confounded - need 1 M milligrams
The Social threats ; Researcher Bias (unintended and intended), Participant bias (social desirability, test anxiety)
