Enter the sum of all variances and the number of results into the Calculator. The calculator will evaluate the Average Error. 

Average Error Formula

AE = SV / n


  • AE is the Average Error ()
  • SV is the sum of all variances
  • NI is the number of results

To calculate Average Error, divide the sum of all errors by the number of results.

How to Calculate Average Error?

The following steps outline how to calculate the Average Error.

  1. First, determine the sum of all variances. 
  2. Next, determine the number of results. 
  3. Next, gather the formula from above = AE = SV / n.
  4. Finally, calculate the Average Error.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

sum of all variances = 575

number of results = 30
