Suppose a researcher wishes to predict weight loss from motivation (based on a scale that ranges from 1=low motivation to 10=high motivation). She collects the data presented below.

Fill in the blank: In a regression line, the ________ the standard error of the estimate is, the more accurate the predictions are.

A). Larger

B). Smaller

C). More positive

D). The standard error of the estimate is not related to the accuracy of the predictions.

************************

The standard error dictates the width of the confidence interval. Wider confidence intervals are less accurate, and higher standard errors produce wider confidence intervals.
