Question

regression is especially problematic in which of the following situations? a. when one group has an extremely high score at pretest b. when the experimental and comparison groups are equal at posttest c. when one group has an extremely low score at posttest d. when the experimental and comparison groups are equal at pretest

Answer 1

Regression is especially problematic in a situation when one group has an extremely high score at pretest. option A is the correct answer.

Market researchers frequently use regression analysis to better understand how independent variables relate to dependent variables. It concentrates more on the relationship between changes in the independent factors and changes in the dependent variable.

You can forecast how the independent variable will affect the dependent one by creating a regression analysis. As an illustration, we can state that a linear regression model can adequately capture age and height. Age and height have a linear relationship because height grows with age.

Regression expresses the relationship as an equation, whereas correlation quantifies the strength of the linear relationship between two variables. To conclude, Regression is problematic in a situation when one group has an extremely high score at pretest.
