H10 Expected Value The expected value of R1 , E[R1 ] or 1 , tells you what the most likely outcome of the random variable R1 is. The denition of an expected value is in equation (1): S 1 = E[R1 ] = R1 (s)p(s) (1) s=1 It is the value of the stock in each e

H9 RESIDUALS Suppose that we use this prediction method for a home that was part of our original data set. The home listed as the first data point had an area of 1,800 square feet. The fitted price would be 88,400 + 55.49 1,800 = 88,400 + 99,882 = 188,282

H9 REGRESSION In most statistical work with two variables, we move beyond the correlation concept to explore the related notion of regression. In the regression context we think of one of the variables as a possible influence on the other. The correlation
