a. The researchers selectively reported the most positive findings

- A confederate chooses which group the participants will belong to
- Participants aren’t randomly assigned
- There is no need for assignment in quasi-experimental designs
d. Participants aren’t randomly assigned
7. A study in which past experiences are recorded based on individual recall or in response to specific questions is often referred to as?
8. What is a possible consequence of running a study with a small sample size, and therefore low power?
- The results may not be reliable
- The results will certainly not be significant
- The study will not get published
- There will be a higher rate of attrition
- The results will likely not be valid
a. The results may not be reliable
9. If one variable (e.g., food intake) was found to be elevated in a group of individuals, and subsequently a second variable (e.g., frequency of obesity) was also found to be high, what kind of relationship between these two variables would you likely conclude there to be?
- Moderated mediation
10. What type of analysis is used to determine whether variables as a group might be more predictive of an outcome than simply knowing about a single variable?
- Grouped analysis
- Normative analysis
- Cluster analysis
- Multiple analysis
c. Cluster analysis
