• Field4 contains one repetition with a value of 3.
VarianceP(Field4) results in an error since the variance of a single value is not
defined.
VarianceP(Field1;Field2;Field3) returns 4.66666666..., 6.22222222..., 2.25, 4
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 population variance for each
class is:
Class 1: 3.26530612...
Class 2: 310.20408163...
The population variance for Class 1 is much lower than the population variance for Class
2 because the scores for Class 1 are more tightly clustered.
