Question

Suppose your professor reports that across all of her classes over the past 10 years, she found a -0.63 correlation between number of absences and final exam score. This statistic means that ______________

Answer 1

Using correlation coefficients, it is found that the -0.63 correlation between number of absences and final exam score means that there is a strong negative correlation between number of absences and final exam score.

What is a correlation coefficient?

It is an index that measures correlation between two variables, assuming values between -1 and 1.

If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.

If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.

In this problem, the correlation is of -0.63, hence:

It means that that there is a strong negative correlation between number of absences and final exam score.
