The cloud of dots starts low and goes up that means it is a positive relationship. So now that you have the general idea of how these things work here are the rules for interpreting correlation coefficients. First cover up the sign and look at the number. The number tells you how strong the relationship is. Correlation coefficients range in strength from .0 to 1.00.
Strength means how linked together they are.
Meaning how likely it is that if you are high on one variable you will be high on the other also. Or if you change one variable will the other change also. A -.99 is stronger than .26 because it has to do with the size of the number not the plus or minus sign. Remember, you cover up the sign to decide how strong the relationship is. Now look at the sign.
