Document Summary
Psyc 203 chapter 10- quasi-experimental designs and applied research. Involves a situation in which research participants cannot be randomly assigned to groups. Includes independent and dependent variables: causal conclusions cannot be made, occurs in applied research that takes place outside of the lab. Interrupted time series designs: archival research involves answering empirical questions by using information already collected for some other purpose rather than by collecting new data. If this occurs, then using a matching procedure can enhance the influence of the regression to the mean problem and even make it appear that a successful program has failed. Interrupted time series designs: taking measures for an extended period before and after the event expected to influence behaviour. Outcomes: main advantage of a time series design is that it allows the researcher to evaluate trends- relatively consistent patterns of events that occur with the passing of time.
