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

r =

(1)

r =
SS(xy)

SS(x) ยท SS(y)

(2) r = 1.00 Incorrect: Your answer is incorrect. .

• statistics -

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.
