Explain the research situations that may require you to use quasi-experimental and single-case experimental methods (be sure to give examples/be specific).
Examine the limitations and benefits learned about these methods and their use.
Analyze any ethical considerations with implementing these methods.
Reflect on your experience with this week’s Review Question activity.
Include any questions you may have for your professor.

Review Questions
A quasi-experimental research design is structured similar to an experiment, with what two exceptions?State whether each of the following factors is an example of an independent variable or a quasi-independent variable. Only state “quasi-independent variable” for participant variables that cannot be manipulated.
The age of participantsTime allotted for taking an examA participant’s work experienceTime of day a study is conductedA participant’s state of residenceAmount of sugar added to a drinkHow does a one-group pretest-posttest design improve on the posttest-only quasi-experimental design? What is the major limitation of all one-group designs?What is a nonequivalent control group, and why does this type of group make it difficult to determine cause and effect using a nonequivalent control group quasi-experimental design?What is the key difference between the basic and interrupted time series quasi-experimental research designs?Name the developmental research design described in each of the following examples:
