O REGRESSION AND CORRELATION
Predictions from the least-squares.
An advertising firm wishes to demonstrate to its clients the effectiveness
of the advertising campaigns it has conducted. The following bivariate
data on fifteen recent campaigns, including the cost of each campaign
(in millions of dollars) and the resulting percentage increase in sales
following the campaign, were presented by the firm. Based on these
data, we would compute the least-squares regression line to be
P-6.24 + 0.15x, with x representing campaign cost and y representing the
resulting percentage increase in sales. (This line is shown in Figure 1,
along with a scatter plot of the data.)
