WebMar 16, 2024 · Additionally, Microsoft Excel allows displaying a trendline equation and R-squared value in a chart: Trendline equation is a formula that finds a line that best fits the data points. R-squared value measures the trendline reliability - the nearer R 2 is to 1, the better the trendline fits the data. WebHow do you calculate R 2 in Excel? The Excel formula for finding the correlation is "= CORREL([Data set 1], [Data set 2]). To find R-squared, select the cell with the correlation formula and square the result (=[correlation cell] ^2). To find R-squared using a single formula, enter the following in an empty cell: =RSQ([Data set 1],[Data set 2]).
