Data Set 6-10: The correlation between a score based on anthropometric measurements (height, strength, reaction time and others) and college GPA is .05. Your task will be to predict GPA, given the anthro measurements. Be sure you set this up properly and work precisely (3 or 4 decimal places.).
$$\begin{array} { l c r }
& \underline{ \text { GPA }} & \underline{ \text { Anthro }} \
\text { Mean } & 2.6 & 20 \
\text { Standard Deviation } & 0.7 & 4
\end{array}$$
-Based on the correlation coefficient in Data Set 6-10, the amount of confidence you should place in a prediction about GPA is
A) absolute
B) a high degree
C) a moderate degree
D) almost no confidence.

Quizplus · Accepted Answer

The correlation coefficient of .05 indicates a very weak relationship between the anthropometric measurements and college GPA, suggesting that predictions about GPA based on these measurements would be unreliable.
