A researcher wants to find out whether increased time on task causes increased achievement. Which research design should she use?

Question

Quizplus · Accepted Answer

An experimental design would be the best choice for this research question because it allows the researcher to manipulate the variable of interest (time on task) and measure its impact on the outcome variable (achievement). By randomly assigning participants to different levels of time on task and measuring their achievement, the researcher can establish cause-and-effect relationships between the two variables. Other designs, such as qualitative or non-experimental correlational, may not provide the same level of control over variables and may not allow for causal inferences. The clinical design is not relevant to this research question.
