How To Calculate RMSE In Excel

Jump to

    Calculating the Root Mean Square Error (RMSE) is a standard procedure to assess the differences between values predicted by a model and the actual observed values. Excel, with its built-in formulas, provides one way to perform this calculation.

    The process involves squaring the residuals, averaging them, taking the square root, and can be executed through a series of steps in Excel. However, for those looking for a more efficient and user-friendly alternative, Sourcetable offers a simpler solution.

    In the following sections, we'll demonstrate the traditional Excel method and explore why Sourcetable can streamline the process of calculating RMSE.

    Calculate RMSE in Excel

    To compute the Root Mean Square Error (RMSE) in Excel, follow a formula that necessitates separate columns for predicted and observed values. Specifically, Excel requires manual formula input to calculate RMSE, as it does not offer a built-in function for this operation. The formula is succinct and directly computes the RMSE by considering the squared differences between the paired values.

    RMSE Formula in Excel

    The standard RMSE formula in Excel is =SQRT(SUMSQ(A2:A21-B2:B21) / COUNTA(A2:A21)), with assumed predicted and observed values in columns A and B, respectively. Apply this formula to calculate the square root of the average of the squared differences.

    Calculating RMSE Step-by-Step

    Calculating RMSE involves a few straightforward steps. Begin by squaring the differences between predicted and observed values. Continue by averaging these squared differences. The process concludes with the extraction of the square root of this average, providing the RMSE.

    Using RMSE for Model Comparison

    RMSE facilitates comparison between various models, with its value indicating how closely a model's predictions match the observed data. Generally, lower RMSE values signify more accurate models, making it a reliable metric for model evaluation in diverse applications.
