Points rise diagonally in a narrow scatter between (0, 1) and (9, 9). A line labeled A is constant and horizontal extending from (0, 7) through (10, 7). A line labeled B increases diagonally extending from (0, 1) through (9, 9). A line labeled C decreases diagonally extending from (0, 8) through (4, 2). All values are estimated. A line that best expresses the relationship between two individual data points is what we call the line of best fit. The lines of best fit are a crucial output of a regression analysis.

The "line of best fit" is a line that shows the pattern of data points. If we can find a good line, it means there is a linear trend. If not, it means there is no linear trend. We can't ignore points that don't fit the trend. Created by Sal Khan. Questions Tips & Thanks Want to join the conversation?
