Document Summary

For all topics described below, be able to describe relevant research. Whenever possible, be able to provide details about research findings from specific studies. Describe the pros/cons of experimental vs. correlational design. Be able to apply this information to evaluate a study (e. g. , identify limitations and alternative explanations). Experimental studies: random assignment to conditions, establish cause and effect relationships. Dependent variable (effect: this study is desirable when you want to know if there is a cause and effect relationship, focuses on the impact of a variable. Correlational studies: associations between 2 or more variables, correlation coefficient = strength (-1 to +1, positive correlation. When 1 variable goes up, the other goes up: negative correlation. When 1 variable goes up, the other goes down: zero correlation. The 2 things aren"t related in any way: correlation does not mean causation, pros. Able to tell you a little about something: this study is desirable when you want to know about a trend.
