VariancePfield - any related field, repeating field, or set of non-repeating fields; or an expression that returns a field, repeating field, or set of non-repeating fields.The variance of a population distribution is a measure of how spread out the distribution is. Field can be any of the following:

• a repeating field (repeatingField).

• a field in matching related records specified by (table::field), whether or not these records appear in a portal.

•

• corresponding repetitions of repeating fields in a record (repeatingField1;repeatingField2;repeatingField3), if the result is returned in a repeating field with at least the same number of repeats.

• several fields in the first matching record specified by (table::field1;table::field2;...). You can include fields from different tables (table 1::field A;table 2::field B...).VarianceP(table::Scores) returns 1.25.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.Class 1: 3.26530612...Class 2: 310.20408163...
