Using a calculator, find the least-squares regression line for predicting values of a response variable, y, from an explanatory variable, x, from the data. Find the slope and intercept of the least-squares regression line for the means and standard deviations of x and y and their correlation. Use the regression line to predict y for a given x.

This line obtained by the least squares method gives the best estimate of a line with least sum of deviation. as calculated quantifies the spread around the regression line. The objective of least squares method is to obtain a compact equation that best describes all the data points. The mean can also be used to describe all the data points.

Fact 3: The least squares regression line of y on x always passes through the point (x bar, y bar). Fact 4: The correlation r explains the strength of a straight line relationship. In the regression setting, this description takes a specific form: the square of the correlation, r2, is the fraction of the variation in the values of y that is ...

The line of best-fit or the least-squares regression line is the line that minimizes the sum of the squared residuals. On the calculator it will be . Relate this equation back to the slope-intercept form for a linear equation, , that you learned in Algebra, where m is the slope and b is the y-intercept.

They fit a least squares regression. line to the data. The graph of the residuals and part of the computer output for their regression are given below. r = 0.88 (a) Is a line an appropriate model to use for these data? What information tells you this? A straight line model is appropriate because there is a random pattern. of residuals in the plot.
