To use your calculator to find the equation of the least squares line, use the STAT CALC menu and select option 8: LinReg(a+bx). You should have the following displayed on your home screen: To find the least squares line for predicting airfare from distance, complete the command by entering the two appropriate lists so that you have the ...
Activity overview:
Compute the sum of the squares of the residuals Encourage your students to try additional lines of “better fit” in order to minimize the sum of the squares of the residuals. A good sum will be somewhere between 41 and 50. Find the line of best fit. The equation of the line of best fit is shown below on the left.

between an observed observation and a predicted or fit value. Graphically, it is the vertical distance between a point and the line of best fit. It is found by subtracting the fitted -value from the observed y-value: An . outlier, in the regression sense, is a value with a large, in absolute value, residual.

The slope is close to zero, signifying that the relationship between strength and functional mobility is weak. Consider the three points (2,11), (3,17), (and (4,29). Given any straight line, we can calculate the sum of the squares of the three vertical distances from these points to the line. What is the smallest possible value this sum can be?

A key pattern for this lesson is the sum of the outer new column and row as the squares grow in size is the difference of consecutive perfect squares. The difference in the models of the consecutive perfect squares 16 and 9 is the addition of 7 X's in the outer column and row. Notice that 7 is the difference between 16 and 9.
