How to Do Linear Regression in Google Sheets
Introduction
Performing linear regression in Google Sheets helps understand relationships between variables. Google Sheets offers the LINEST function, making regression analysis accessible and efficient.
Using the LINEST Function
Use the LINEST function to perform linear regression in Google Sheets. The syntax is LINEST(known_y's, known_x's, [const], [stats]).
Arguments for LINEST Function
The first argument, known_y's, is required and refers to the range of cells with the dependent variable.
The second argument, known_x's, is required and refers to the range of cells with the independent variable(s).
The third argument, const, is optional. Set it to TRUE or omit to calculate the y-intercept.
The fourth argument, stats, is optional. Set it to TRUE to return additional regression statistics.
Steps for Simple Linear Regression
First, input your data into Google Sheets. Then, select an empty cell for the LINEST output.
Type =LINEST(known_y's, known_x's) into the formula bar and press Enter. The output will display the slope and y-intercept of the regression line.
Visualizing the Relationship
Highlight both the independent and dependent variable data. Insert a scatter plot to visualize the data.
Add a trendline to the scatter plot to represent the linear regression line.
Getting Additional Statistics
To get more regression statistics, set the last two parameters in the LINEST function to TRUE. The function will return statistics like the standard error and R-squared value.
Conclusion
By following these steps, you can perform linear regression efficiently in Google Sheets, helping you analyze and visualize relationships between variables.
