? Question 2 10 out of 10 points
An imperfect relationship generally yields exact prediction.
? Question 3 10 out of 10 points
If the correlation between two variables is 1.00, the standard error of estimate equals 0.
? Question 4 10 out of 10 points
If X and Y are plotted as standard (z) scores, then r equals the slope of the resulting regression line.
? Question 5 10 out of 10 points
To do linear regression, there must be paired scores on two variables.
? Question 6 10 out of 10 points
Pearson r is the slope of the least squares regression line when the scores are plotted as z scores.
? Question 7
10 out of 10 points
When there are two predictor variables, R2 is the simple sum of r2 for the relationship of the first predictor variable and Y and r2 for the relationship of the second predictor variable and Y.
? Question 8 0 out of 10 points
When doing regression, it is customary to assign X to the predicted variable.
? Question 9 10 out of 10 points
If sY = sX, then r = bY.
? Question 10 0 out of 10 points
If we minimize ? (Y?Y’)2, we will minimize the total error of prediction.
