Summary Of Probability & ANOR

• The probability of X and Y occurring at the same time equals the probability of X times the probability of Y.
• The probability of X or Y occurring (either one) is the addition of the probability of X and the probability of Y.
• Analysis of Regression tests the likelihood that the linear relationship between the two variables is due to chance. A significant F indicates that X predicts Y well and that the relationship between the two variables is not likely to be due to chance.
• Analysis of Regression does not prove cause and effect. X may cause Y or Y may cause X, or both could be caused by another variable.
