WebJan 17, 2024 · A regression line, or a line of best fit, can be drawn on a scatter plot and used to predict outcomes for the \(x\) and \(y\) variables in a given data set or sample data. There are several ways to find a regression line, but usually the least-squares regression line is used because it creates a uniform line. WebEach point of data is of the the form ( x, y) and each point of the line of best fit using least-squares linear regression has the form ( x, ŷ ). The ŷ is read "y hat" and is the estimated value of y. It is the value of y obtained using the regression line. It is not generally equal to y … Introductory Statistics follows scope and sequence requirements of a one-semest…
