A line of best fit is drawn through a scatterplot to find the direction of an association between two variables. This line of best fit can then be used to make predictions. To draw a line of best fit, balance the number of points above the line with the number of points below the line. Example 13Theme. Copy. % Get coefficients of a line fit through the data. coefficients = polyfit (x, y, 1); % Create a new x axis with exactly 1000 points (or whatever you want). xFit = linspace (min (x), max (x), 1000); % Get the estimated yFit value for each of those 1000 new x locations. yFit = polyval (coefficients , xFit); % Plot everything.

Step 4: Choose the Best Trendline. From the plot above, it’s clear that the linear trendline does a poor job of capturing the behavior of the data. Instead, we can choose to fit a polynomial curve. To do so, click the dropdown arrow under Type and choose Polynomial. Then click the dropdown arrow under Polynomial degree and choose 4.
