Where x and y are the sample means AVERAGE(known_x’s) and AVERAGE(known_y’s). The equation for the Pearson product moment correlation coefficient, r, is: If known_y's and known_x's contain only 1 data point, RSQ returns the #DIV/0! error value. If known_y's and known_x's are empty or have a different number of data points, RSQ returns the #N/A error value. If an array or reference argument contains text, logical values, or empty cells, those values are ignored however, cells with the value zero are included.Īrguments that are error values or text that cannot be translated into numbers cause errors. Logical values and text representations of numbers that you type directly into the list of arguments are counted. An array or range of data points.Īrguments can either be numbers or names, arrays, or references that contain numbers. The RSQ function syntax has the following arguments: The r-squared value can be interpreted as the proportion of the variance in y attributable to the variance in x.
For more information, see the PEARSON function. Returns the square of the Pearson product moment correlation coefficient through data points in known_y's and known_x's. This article describes the formula syntax and usage of the RSQ
