Exam 2: Studying Groups Scientifically

Which of the following refers to an analysis that systematically selects existing research and uses the effect size statistic to draw conclusions about the research literature?

What are the goals of observational, correlational, and experimental research? What are the advantages and disadvantages of each research approach?

If we find that there is a positive correlation between group cohesion and group performance, which of the following is true?

Define basic research and applied research. Give an example of each type, other than those mentioned in Chapter 2. How do these two types of research relate to each other?

Consider how network analysis and SYMLOG are used to organize data and to understand group behavior in observational studies.

Describe a correlational research design that might be used to test the research hypothesis that increases in group size lead to decreases in group cohesion. Describe the operational definitions of the predictor and outcome variables, and explain why the correlational design does not allow us to draw conclusions about causal relationships between them.

Leslie has developed a prediction about group behavior that proposes that people will be happier in smaller groups than in larger groups, because there is more interaction and interdependence in smaller groups. Leslie has developed which of the following?
