R Square equals 0.962, which is a very good fit. 96% of the variation in Quantity Sold is explained by the independent variables Price and Advertising. The closer to 1, the better the regression line (read on) fits the data.
To check if your results are reliable (statistically significant), look at Significance F (0.001). If this value is less than 0.05, you're OK. If Significance F is greater than 0.05, it's probably better to stop using this set of independent variables. Delete a variable with a high P-value (greater than 0.05) and rerun the regression until Signific...
The regression line is: y = Quantity Sold = 8536.214 -835.722 * Price + 0.592* Advertising. In other words, for each unit increase in price, Quantity Sold decreases by 835.722 units. For each unit increase in Advertising, Quantity Sold increases by 0.592 units. This is valuable information. You can also use these coefficients to do a forecast. For ...
The residuals show you how far away the actual data points are from the predicted data points (using the equation). For example, the first data point equals 8500. Using the equation, the predicted data point equals 8536.214 -835.722 * 2 + 0.592 * 2800 = 8523.009, giving a residual of 8500 - 8523.009 = -23.009. You can also create a scatter plot of ...
