x y

1 -1/4

2 -1/2

3 -3/4

4 ?

* would the correlation between x and y in the table show above be positive or negative? i think that it would be negative, i am not sure that is correct?

* find the value of y in the table? i think that it is 4/4 or 1, is that correct?

* how would the values of this table be interpreted i terms of linear regression? please explain.

thank you. mary hornbeck

**PsyDAG**, Tuesday, October 19, 2010 at 10:54amWhen x increases by 1, y increases by 1/4. 1 is correct, but if both variables increase, is that a positive or negative correlation?
