R-squared, also known as the coefficient of determination, is the statistical measurement of the correlation between an investment’s performance and a specific benchmark index. In other words, it shows what degree a stock or portfolio’s performance can
A formula for R – Squared is given by: R– Squared = 1 – (Sum of First Errors / Sum of Second Errors) Examples of R – Squared Formula (With Excel Template) Let’s take an example to understand the calculation of R – Squared in a better manner. ...
Learning to calculate a correlation is crucial, and you can easily find the "r value" in Excel using either built-in functions or by working through the calculation in pieces using the more basic functions of the program. The simplest way is using the built-in function, but understanding the...

R-squared represents the proportion of the variance in the dependent variable that is predictable from the independent variables. A value of 1 implies that all the variability in the dependent variable is explained by the independent variables, while a value of 0 suggests that the independent varia...
Enter this information in an empty cell to find R-squared using a single formula: =RSQ([Data set 1],[Data set 2]).3 The Bottom Line R-squared is a statistical measure that explains the variance of one variable using the variance of another. The initial result of the calculation isn’...
