Go to calculatorAre you looking for an easy way to analyze relationships between variables in your data? Our Linear Regression Calculator is the perfect tool to help you uncover trends and make predictions. Whether you’re a student, researcher, or business professional, this calculator simplifies complex statistical analysis, saving you time and effort.
Note: This calculator provides a basic linear regression analysis. For more complex analyses or professional advice, consult a statistician.
Linear regression is a statistical method used to model the relationship between two variables by fitting a linear equation to observed data. It’s widely used in various fields, including economics, biology, and social sciences, to understand and predict trends.
After using the calculator, you’ll receive the following information:
The slope indicates how much y changes for each unit increase in x. A positive slope means y increases as x increases, while a negative slope means y decreases as x increases.
This is the predicted y value when x equals zero. It may or may not have a meaningful interpretation depending on your data.
Now that you understand how to use and interpret linear regression, it’s time to analyze your own data. Our Linear Regression Calculator makes it easy to get started. Whether you’re working on a school project, scientific research, or business analysis, this tool will help you uncover valuable insights.

Correlation measures the strength and direction of a relationship between variables, while regression provides a mathematical equation to predict one variable based on another.
Yes, multiple linear regression allows you to analyze relationships between multiple independent variables and one dependent variable.
Check if there's a roughly linear relationship between your variables by creating a scatter plot. Also, ensure your data meets the assumptions mentioned in the tips section.
You might need to consider non-linear regression models or transform your data to achieve linearity.
Generally, the more data points, the better. A minimum of 30 points is often recommended, but this can vary depending on your specific situation.
