What Is the Line of Best Fit?
- A line of best fit is a straight line that minimizes the distance between it and some data.
- The line of best fit is used to express a relationship in a scatter plot of different data points.
How do you find the equation of best fit?
The line of best fit is described by the equation ŷ = bX + a, where b is the slope of the line and a is the intercept (i.e., the value of Y when X = 0). This calculator will determine the values of b and a for a set of data comprising two variables, and estimate the value of Y for any specified value of X.
