Inverse Relationship | Inverse Relationships in Economics, Finance, Both variables are on an interval or ratio. The correlation is moderate to strong. Hence we can conclude that the r-value option (D) -0.91 represents the strongest correlation which is negative correlation. If you have two lines that are both positive and perfectly linear, then they would both have the same correlation coefficient. As a rule of thumb, a correlation greater than 0.75 is considered to be a strong correlation between two variables. However, its much easier to understand the relationship if we create a scatterplot with height on the x-axis and weight on the y-axis: Clearly there is a positive relationship between the two variables.

What is Considered to Be a Weak Correlation What is description of how the researchers will measure the variables of interest? The value r = 0.02 in choice C is the closest to r = 0, so this correlation is the weakest among the group of other r values. Simply expecting something to happen can make it happen.
