- Would the correlation between x and y in the table above be positive or negative?

- Find the missing value of y in the table.

- How would the values of this table be interpreted in terms of linear regression?

- If a “line of best fit” is placed among these points plotted on a coordinate system, would the slope of this line be positive or negative?

**PsyDAG**, Friday, November 11, 2011 at 11:18amPositive correlation means both variables increase/decrease together. Negative correlation means one variable increases while the other decreases.

What is the consistent difference between the y values to determine the missing value?

How good is the predictability of y from x?

Slope value (±) is the same as the correlation value (±).
