• Field1 contains two repetitions with values of 1 and 2.
• Field2 contains four repetitions with values of 5, 6, 7, and 8.
• Field3 contains four repetitions with values of 6, 0, 4,and 4.
• Field4 contains one repetition with a value of 3.
Variance(Field4) results in an error since the variance of a single value is not defined.
Variance(Field1;Field2;Field3) returns 7, 9.33333333..., 4.5, 8 if the calculation is a
repeating field.
Student example
Two classes of students take an exam. Class 1 has scores of 70, 71, 70, 74, 75, 73, 72 and
Class 2 has scores of 55, 80, 75, 40, 65, 50, 95. The variance for each class is:
Class 1: 3.80952380...
Class 2: 361.90476190...
The variance for Class 1 is much lower than the variance for Class 2, because the scores
for Class 2 are more spread out.
