What is the regression threat in a single group design?
What will be an ideal response?
A regression threat to internal validity, also known as a regression artifact or regression to the mean, is a statistical phenomenon that falsely makes it appear that your group changed to be more like the overall population between the pretest and posttest. If your group was above the population average on the pretest, they will look like they lost ground on the posttest. If they were below the population average on the pretest, they will falsely appear to improve. Regression occurs whenever you have a nonrandom sample from a population and two measures that are imperfectly correlated.
