#### Formula :

MSE = SSE / n
**Where,**
MSE = Mean Squared Error
SSE = Sum of Squared Error
n = Number of Population
Calculate the mean squared error and sum of squared error using this simple online mean squared error calculator. Just enter the population values in this sum of squared error calculator to know the squared errors.

**Mean Squared Error (MSE):**
It is a measure of how close a fitted line is to data points. It is an average of the squares of the difference between the actual observations and the predicted observations. The Mean Squared Error is used to forecast accuracy in business analysis and supply chain management.

MSE is just the sum of squared errors divided by the number of population or the values in the data range. It comprises the variance of the estimator and the squared bias. Mathematically, MSE is calculated by finding the regression line, insert the X values into the linear regression equation to find the new Y values (Y'), subtract the new Y value from the original to get the errors, square the errors, sum the errors and finding the mean.
