Small letters refer to deviation scores. Multiply the deviation score for each x value by the corresponding deviation score for each y value. Then add these values together.
(-2)(0) + (0)(-1) + (2)(1) = 2
What is the effect on the correlation of adding 12 to every score on one variable?

true
false
The correlation may go up or down, it depends on the data.
false
The correlation will increase.
true
The correlation will not change.
The correlation will not change. Since the scores are converted to deviation scores, adding 12 will have no effect.
