Document Summary
Week 11 lecture #9. 5 wednesday, july 22, 2015. Experiment design best for validity and reliability. Since everything is the same except for the manipulated variable, so high reliability. But not every study can be a experimental design ethnical problems. Describe single case experimental designs and discuss reasons to use this design. Describe the five types of evaluations involved in program evaluation research: needs assessment, program assessment, process evaluation, outcome evaluation, and efficiency assessment. Describe the one-group pretest-posttest design and the associated threats to internal validity that may occur: history, maturation, testing, instrument decay, and regression toward the mean. Describe the nonequivalent control group design and nonequivalent control group pretest-posttest design, and discuss the advantages of having a control group. Distinguish between the interrupted time series design and control series design. Describe cross-sectional, longitudinal, and sequential research designs, including the advantages and disadvantages of each design.
