The range of values for a correlation is from 0 to 1. d. All of. If the relationship between taking a certain drug and the reduction in heart attacks is r = 0.3, this might be considered a weak positive relationship in other fields, but in medicine its significant enough that it would be worth taking the drug to reduce the chances of having a heart attack. To interpret its value, see which of the following values your correlation r is closest to: Exactly 1. Section I: Conceptual Questions - 20 marks b.

What does the "n - 1" in the denominator of a correlation formula indicate? The sign (+ or -) represents the direction, while the numerical value represents the strength of the relationship between the two variables. \begin{matrix} x & 3 & 8 & 3 & 6 & 6\\ y & 7 & 9 & 5 & 5 & 6 \end{matrix}, B) specify the competing hypothesis in order to determine wether there is a negative population correlation between the number of rainy days and crime.
