Question

Quizplus · Accepted Answer

Random assignment is the process of assigning participants to either the control or experimental group in a way that minimizes differences between the groups. This helps to ensure that any differences in the outcomes between the two groups can be attributed to the intervention being studied rather than pre-existing differences between the groups. Replication is the process of repeating a study to see if the same results can be obtained and is not a method used to minimize differences between groups. Random sampling is the process of selecting a sample that is representative of the larger population, but it is not used to minimize differences between groups. Correlation is a statistical measure of the relationship between variables and is not a method used to minimize differences between groups.
