Suppose You Compute the Correlation Coefficient Between Two Variables, X

question 50

Multiple Choice

Suppose you compute the correlation coefficient between two variables, X and Y, and obtain a value of 0.55.Then you realize that all the values for both variables have been corrupted in a way that their actual sign has been changed (positive values were turned into negative values and vice versa; only the signs have been changed) .Then the actual, corrected value of the correlation coefficient ______.

• A)is −0.55
• B)remains unchanged
• C)changes but there is not enough information to determine the correct value
• D)is 0
• E)is 0.50
