Question

Quizplus · Accepted Answer

The most appropriate design to evaluate the effectiveness of a program is the time series with nonequivalent control group design. This design compares the outcomes of the program before and after its implementation and also compares the outcomes of the program with a group that did not receive the program. This allows the researcher to isolate the effects of the program from other factors that could have influenced the outcome.
