Frequently Asked Questions
The line of best fit is a straight line that best represents the data on a scatter plot. It is calculated using linear regression to minimize the sum of squared errors.
Enter your x and y values as comma-separated numbers (e.g., 1,2,3 for x and 2,4,5 for y). Then click Calculate to get the slope, intercept, and R-squared value.
R-squared (R²) is a statistical measure that represents the proportion of the variance for the dependent variable that's explained by the independent variable. Values range from 0 to 1, with higher values indicating a better fit.
