A positive slope suggests a positive relationship between X and Y, while a negative slope implies an inverse relationship. The slope indicates the rate of change in the Y variable per unit change in the X variable. For example, if the equation is ŷ = 0.5X + 1, it means that for every unit increase in X, the predicted value of Y will increase by 0.5. The coefficient 'b' indicates the slope, and 'a' represents the intercept. This equation represents the relationship between the X and Y variables. How to Interpret Linear Regression Calculator Results Use these instructions to effectively utilize the Linear Regression Calculator for data analysis. Repeat or modify: You can repeat the process by entering new data points or modify the existing ones to explore different scenarios and observe how the regression analysis changes. This visual representation can provide further understanding of the data.ĥ. Visualize the fitted line plot: Below the results, a chart will be generated showing the data points and the fitted line based on the regression analysis. These insights will help you understand the relationship between the X and Y variables.Ĥ. View the results: The calculator will display various results, including the regression equation, slope, intercept, R-squared, correlation coefficient, and more. Click the "Calculate" button: After entering your data points, click the "Calculate" button to perform the linear regression analysis.ģ. Enter your data points: In the input fields labeled "X values" and "Y values," enter your data points separated by commas or spaces.
