1. the correlation gives us information as to how strong the linear association is between two quantitive variables
2. the correlation coefficient has units of measurement and dose always lie -1.0 and +1.0
3. the closer the absolute value of r is to 0 the stronger the relationship is between the two variables
4.a correlation coefficient of r = 0 indicates a strong linear relationship between two variables
5.a correlation coefficient of r = -0.9 indicates a weak linear relationship between two variables
6. two variables can be correlated without one causing the other
