Given a scatter plot, we can draw the line that best fits the data. The formula of the regression line for y on x is as follows: Often the questions we ask require us to make accurate predictions on how one factor affects an outcome. Web are you asking how to compute it, draw it, or both? Web regression analysis draws a line through these points that minimizes their overall distance from the line. More specifically, least squares regression minimizes the sum of the squared differences between the data points and the line, which. Web in this video we discuss how to construct draw find a regression line equation, and cover what is a regression line equation. The formula derived in this video directly minimizes the sum of squared errors, while the formula involving r relates the slope to the strength and direction of the linear relationship between x and y.
