B)regression constant.
C)proportionate reduction in error.
D)standardized regression coefficient.

Quizplus · Accepted Answer

The slope in a regression equation represents the amount by which the predicted outcome variable changes for a one-unit increase in the predictor variable. The regression coefficient is the numerical value of the slope, which indicates the strength and direction of the relationship between the two variables. In this case, the slope of -2 means that for every one-point increase in test anxiety, there is a decrease of two points in predicted test performance. Therefore, the best choice is A) regression coefficient.
