The sum of squared errors is the sum of the squared differences between the actual values and the predicted values. In this case, the actual values are the values of the dependent variable, and the predicted values are the values of the independent variable. The sum of squared errors is calculated as follows:SSE = Σ(y - ŷ)²where:y is the actual valueŷ is the predicted valueΣ is the sum of the valuesIn this case, the sum of squared errors is 35,191.91.
