Answer:

Strong positive

Explanation:

In studies, we usually establish relationships between two or more variables using correlations. Correlations tell us how this variables are related.

  • Two variables have a positive correlation when if one increases the other increases too.
  • Two variables have a negative correlation when if one increases the other decreases and vice versa.

Also, a correlation can be weak, moderate or strong. Researchers agree that a correlation that is larger than 0.70 should be considered a strong correlation.

In this example Isabella reads about a study saying there's a correlation coefficient of +0.85 between hours spent studying and final exam grade. <u>The fact that the sign of this correlation is "+" tells us that it is positive</u> (the more hours spent studying, the better final exam grade). We can also see that <u>the coefficient is 0.85 which is greater than 0.70 and therefore we can consider this correlation as a strong one.</u>

Thus, Isabella would conclude that this is a strong positive relationship.
