A correlation coefficient of r = 0.799 means what?

the two parameters inversely correlate and the relationship is weak
the two parameters directly correlate and the relationship is strong
there is no correlation between the two parameters
the data is insufficient to determine the relationship

The correct answer is: the two parameters directly correlate and the relationship is strong

A correlation coefficient of r = 0.799 indicates a strong positive relationship between the two parameters being analyzed. This means that, as one parameter increases, the other parameter also tends to increase. This value falls within the range of 0.5 to 1.0, indicating a relatively strong correlation. Options A and C can be eliminated as they are both contradictory to the given correlation coefficient. Option D can also be eliminated as there is sufficient data to determine the relationship between the two parameters.
