T ehalf of your GRE D Question 24 1 pts In an experiment, I want to use random assignment so that this is a randomized experiment because those types of experiments are such a strong tool in understanding cause and effect for a behavior. What is it that random assignment does to make it such a good technique in research? o A The use of random assignment creates "blank slates" out of the participants in the different conditions for the IV to write upon (i.e., isolates the IV as the only factor creating the behavior) B. The use of random assignment assures that the sample represents the population. C. The use of random assignment separates the IV from the DV. O D. The use of random assignment creates a natural control group out of the participants so that a participant IV as part of the study, which allows us to use its natural expression as a factor in creating the behavion. we can have E. The use of random assignment comes before the use of random sampling, which allows us to know that the sample represents the population.Explanation / Answer
The answer is Option A. In a way, random assignment does creat blank slates out of the participants because they are distributed in different conditions without any fixed criteria. Thus, differences between the different groups are minimised. This allows the researcher to better study the effect of the IV, as any other extraneous variable relating to the participant’s characteristics that might impact the IV-DV relationship is addressed.
