How to Use the Linear Regression Calculator?

  1. First, input the predictor (X) and response (Y) values with a comma or space separator. Example: 6,10,1,17 or 6 10 1 17.
  2. Press the 'Calculate' button.
  3. Finally, the tool returns the linear regression equation (with slope and intercept) and R-squared value associated with the given data points.
  4. The tool also shows the step-by-step calculation summary and interpretation.

Equation:

y = mx + b

Where,
m = Slope,
x = Independent (predictor) variable,
b = Intercept (value of y when x = 0).
