Linear Regression Calculator

Overview

This tool computes a best fit line from your data pairs. You get the equation, slope, y-intercept, correlation coefficient, and R-squared value.

How It Works

Enter each pair of numbers on a new line. The calculator reads the data and computes the averages. It then calculates the slope and y-intercept. The tool also computes R-squared to show the variance explained.

How to Use This Tool

Step 1: Enter your data pairs in the text box. Each pair should be written as two numbers separated by a comma.

Step 2: Click the "Calculate" button.

Step 3: Review the regression equation and statistical details that appear below the button.

Input Explanation

The text box accepts pairs of numbers. Write each pair in the format x,y. For example, write "1,2" on one line. This format is required for accurate results.

Output Description

The results include the linear regression equation. The slope and y-intercept show the line's direction. The correlation coefficient and R-squared value reveal the fit quality. These values help you understand your data better.

Limitations and Special Notes

You need at least two valid data pairs to perform the analysis. All entries must be numeric. Extra text or symbols may lead to errors.

Common Use Cases

This linear regression calculator is useful for homework projects. It helps when preparing work reports. It suits quick checks on data sets. Both students and professionals find it helpful.

Final Thoughts

This tool makes linear regression analysis simple and quick. It shows clear statistical feedback with little effort. Use it for your next data project and see how simple math reveals key trends.
