The answer should be a negative number as the numbers increase as x becomes smaller.
The correlation coefficient lies between -0.2 and -0.3.
Please post your equation for r again to see if it is interpreted correctly.
Most of the time mistakes come from incorrect interpretation of expressions.
Consider the following table and use the formulas that are given for computing the correlation coefficient. (Give your answer correct to two decimal places.)
x 1 1 0 0 0
y 7 3 5 6 6

SS(x) · SS(y)
(2) r = 1.00 Incorrect: Your answer is incorrect. .
