D.involving skepticism.
Explanation / Answer
1. Known as hindsight bias
Hindsight bias is seeing after an incident had occured as if it was all predictable. This can be avoided by formulating testable predictions before conducting research.
2. b) generalizing from vivid cases
Ervin generalized that african-americans are good player from cases of majority of them playing well.
3. a) the participants are representative of the population they are interested in studying.
4.c) correlation coefficient
