For the table that follows, answer the following questions:
x y
1 8
2 11
3 14
4
 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?

Positive 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 (±).
