In a single prediction question (Y=a + bX), Y represents a(n)
A) predicted criterion score.
B) distribution of scores in the sample.
C) individual's score.
D) constant calculated from the scores.

Question

Quizplus · Accepted Answer

In the regression equation Y=a+bX, Y represents the predicted criterion score, which is the dependent variable that is being predicted by the independent variable X with the help of the regression coefficients (a and b). Therefore, option A is the correct choice. Option B is incorrect because Y is not a distribution of scores, but a single predicted score. Option C is incorrect because Y is not an individual's score, but a predicted score based on a given value of X. Option D is incorrect because the constant is represented by the intercept (a) in the regression equation, while Y represents the predicted criterion score.
