Introduction

Learn to calculate the coefficient of determination, R², in Excel to assess the predictive power of your data models. This metric reflects the proportion of variability in a dependent variable that is predictable from independent variables.

While Excel requires manual manipulation of formulas and functions, Sourcetable's AI chatbot can instantly calculate R² and perform complex statistical analyses through natural language commands. Try Sourcetable to effortlessly analyze data of any size, create visualizations, and get instant answers to your spreadsheet questions.

Calculating the Coefficient of Determination in Excel

Built-in R-squared Formula

To calculate R-squared using Excel's built-in formula, select the cell where you want the result to appear, enter =RSQ([Data set 1], [Data set 2]), and press Enter. Excel requires two data sets, representing the independent and dependent variables, to compute the R-squared value, reflecting how well data fits the regression model.

Using CORREL Function

Alternatively, calculate correlation with =CORREL([Data set 1], [Data set 2]). To find R-squared, square the correlation result in Excel, offering insight into the variance explained by the independent variable.

Formula for R2

The coefficient of determination can also be determined using the formula R2 = 1 - (RSS/TSS), where RSS stands for residual sum of squares, and TSS denotes total sum of squares. This method reveals the proportion of variance in the dependent variable that the independent variable accounts for.

Adjusted R-squared Formula

For multiple regression models, use the adjusted R-squared formula 1 - (1 - R2)*(n - 1)/(n - k - 1), where n is the number of data points, and k is the number of variables. Adjusted R-squared compensates for the number of variables and provides a more accurate measure of the goodness of fit.

Frequently Asked Questions

What is the simplest way to calculate R-squared (coefficient of determination) in Excel?

The simplest way is to use the RSQ function. Type =RSQ(known_y's, known_x's) in a cell, where known_y's are your dependent variable values and known_x's are your independent variable values. For example: =RSQ(A:A,B:B)

What are the different methods to calculate R-squared in Excel?

There are four main methods to calculate R-squared in Excel: 1) Use the RSQ function, 2) Use the LINEST function, 3) Add a trendline to a scatter plot and display the R-squared value, 4) Use the Data Analysis ToolPak's regression analysis

How do I show R-squared on a scatter plot in Excel?

To show R-squared on a scatter plot: 1) Highlight your data, 2) Go to the Insert tab, 3) Select Scatter (X, Y) Chart, 4) Right click on the data points, 5) Select Add Trendline, 6) Check the 'Display R-squared value on chart' box
