What is the Regression Line Equation Calculator?

The Regression Line Equation Calculator is a statistical tool that helps users determine the best-fit line for a dataset using linear regression. By entering X (independent) and Y (dependent) values, the calculator computes the slope and intercept of the regression line, generates predicted Y values for each X, and displays a regression table. This allows users to analyze trends, make predictions, and understand the relationship between variables.

How to Use:

1. Enter X Values (comma-separated): Input the independent variable data points, e.g., 1, 2, 3, 4, 5.
2. Enter Y Values (comma-separated): Input the dependent variable data points corresponding to each X, e.g., 2, 4, 5, 4, 5.
3. Click “Calculate”: The calculator computes the slope, intercept, regression line equation, and predicted Y values.
4. Review Result: The output displays the regression equation and a table showing X, actual Y, and predicted Y (Ŷ) for each point, allowing you to visualize and analyze the data trend.
