WebThe line of best fit is determined by the correlation between the two variables on a scatter plot. In the case that there are a few outliers (data points that are located far away from the rest of the data) the line will adjust so that it represents those points as well. WebFitting a Regression Line to a Set of Data . Once we determine that a set of data is linear using the correlation coefficient, we can use the regression line to make predictions. As we learned above, a regression line is a line that is closest to the data in the scatter plot, which means that only one such line is a best fit for the data.

Web20 feb. 2024 · Because linear regression is nothing else but finding the exact linear function equation (that is: finding the a and b values in the y = a*x + b formula) that fits your data points the best. Note: Here’s some advice if you are not 100% sure about the math. WebUse the regression equation to explain your reasoning. LaTasha is correct. There is no correlation between x and y. The slope of the line of best fit is zero, which shows that there is no negative or positive correlation.
