Method 1 – Apply the SUMSQ Function to Calculate the Root Mean Square Error in Excel Case 1.1 – Using SQRT and COUNTA Steps: Select cell C10. To get the root mean square error, use the formula: =SQRT(SUMSQ(B5:B8-C5:C8)/COUNTA(B5:B8)) Here, the range B5:B8 indicates the Expecte...
Secondly, we can utilize theAVERAGEfunction to calculate the root mean square error in Excel. In this case, we must first get the differences’ square. Then, we can process to obtain the mean square error. Lastly, we can finally get the root mean square error. In this case, our data s...
The signal x(t) is approximated to a sinusoidal function x(t)=4Πsintx(t)=4Πsint sin 𝑡 over the interval [0, 2π]. Evaluate the mean square error in this approximation. Solution The approximation of the rectangular function x(t) by a sinusoidal signal sin 𝑡 is shown in ...

Cell D2 is the root mean square error value. And save your work because you’re finished. If you have a smaller value, this means that predicted values are close to observed values. And vice versa. What’s Next? RMSE quantifies how different a set of values are. The smaller an RMSE...
Root Mean Square Error (RMSE) is a performance measure defined as the square root of the expectation of the squared difference between estimated and actual values. It is commonly used in assessing the accuracy of parameter estimates. AI generated definition based on: Developments in Water Science,...
