How does holding a variable constant prevent the variable from becoming a confound?How does holding a variable constant prevent the variable from becoming a confound? It eliminates the possibility that the variable will be substantially different from one group to another.
Which approach is most effective in preventing confounding by participant characteristics?Randomization in a Clinical Trial
The ideal way to minimize the effects of confounding is to conduct a large randomized clinical trial so that each subject has an equal chance of being assigned to any of the treatment options.
What strategy do researchers use to hold participant characteristic constant?Hold the participant characteristic constant. The correct answer is B, randomly select the participants from the population. In a between-subjects experiment, participants are assigned to treatments using random assignment. Why is random assignment used?
Which approach is most effective in preventing confounding by participant characteristics quizlet?The strongest method of controlling for intrinsic (subject) factors is randomization. It is the most effective method of controlling participants' characteristics. Homogeneity occurs when people who are similar in respect to confounding variables are included in the study.
