Question

A correlation between college entrance exam grades and scholastic achievement was found to be -1.08. On the basis of this you would tell the university that _________.

Answer 1

Answer:

The correlation computed is incorrect.

Step-by-step explanation:

Correlation is a statistical concept used to define the strength of linear relationship between two variables.

The correlation coefficient is computed using the formula:

$r(X,Y)=\frac{Cov(X,Y)}{\sigma(X)\sigma(Y)}$

The range of r is -1.00 to +1.00.

A value of r = -1.00 indicates a strong negative correlation and r = +1.00 indicates a strong positive correlation.

In this case the correlation between college entrance exam grades and scholastic achievement was found to be -1.08.

This cannot happen because the value of r lies in the range -1.00 to +1.00.

The correlation computed is incorrect.
