In many industries, being able to forecast values is a necessary skillset to have. In order to measure the effectiveness of predictions, it’s essential to compare the predicted values to the actual, observed values. One of the measures that make measuring the effectiveness of a predictive model simple, is the mean absolute error (or MAE). …
The root mean squared error (or RMSE) measures how large the error (or difference) is between two datasets. It’s often used to be able to calculate the effectiveness of different types of modeled data, comparing predicted and actual values. In this tutorial, you’ll learn how to calculate the root mean squared error in Excel. While …

The R-squared (or r2) is a measure that represents how much variation of a dependent variable is explained by the independent variable. The higher the value of r-squared, the more of one variable’s variance is explained by the variance of another. In this tutorial, you’ll learn how to use Excel to calculate the r-squared value. …
The mean squared error is frequently used to measure the accuracy of the prediction of a dataset. In this tutorial, you’ll learn how to calculate the mean squared error in Excel. First, you’ll learn how the MSE is calculated and what it represents. Then, you’ll learn how to calculate the mean squared error using Excel. By …
