Researchers use single factor experimental designs to try to study causal relationships. For example, if researchers want to know if an exercise intervention reduces depression, they might randomly assign some participants to receive the exercise intervention and others to not.
They could collect baseline and post-intervention data and compare the two groups. If the treatment group showed a significantly greater reduction of depression than the control group, the researchers would conclude that the exercise intervention reduced depression.

For this research, the focus will be on investigating whether a mindfulness-based stress reduction (MBSR) program can effectively decrease perceived stress levels among college students. The primary research question is: "Does participation in an MBSR program lead to a significant reduction in perceived stress among college students?" The corresponding hypothesis posits that students who participate in the mindfulness program will experience a greater reduction in perceived stress compared to students who do not participate in the program.
To test this hypothesis, I would design a between-subjects experiment, where students are randomly assigned to either the experimental group (participating in the MBSR program) or the control group (not participating). The choice of a between-subjects design is appropriate here because I want to compare the effects of the intervention across different individuals, minimizing the risk of carryover effects or fatigue that can occur with within-subjects designs. This approach ensures that the changes in stress levels can be attributed more confidently to the intervention itself without confounding effects from repeated measures within the same participant.
Random assignment is crucial in this experimental setup because it helps control for confounding variables such as baseline stress levels, personality traits, or prior mindfulness experience. By randomly distributing these factors, we can ensure that groups are comparable at the start, thereby enhancing the internal validity of the study (Passer, 2014).
Regarding sampling, I would opt for random sampling from the college population to improve the external validity or generalizability of the findings. Random sampling ensures that the sample accurately reflects the broader college student population, increasing the reliability of applying the results beyond the sample studied. While random sampling is ideal for generalizability, random assignment within the study is more critical for establishing causal relationships, which is the primary aim here.
In summary, this study would utilize a between-subjects design with random assignment to test the effectiveness of an MBSR program on perceived stress reduction among college students, complemented by random sampling to enhance the external validity of the findings. This approach aligns with principles from research methodology (Passer, 2014) and provides a robust framework for causal inference.
