Description
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.
• several non-repeating fields in a record (field1;field2;field3...).
• 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...).
Examples
A portal displays the related values 5, 6, 7, and 8 in the field Scores. StDevP(table::Scores)
returns 1.11803398....
In the following examples:
• 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.
StDevP(Field4) results in an error because the population standard deviation of a single number
is not defined
.
StDevP(Field2) returns 1.11803398... for a non-repeating field.
StDevP(Field1;Field2;Field3) returns 2.16024689..., 2.49443825..., 1.5, 2 for repeating
fields.
Note When a referenced field is a repeating field, the StDevP function returns the standard
deviation of a population in the first repetition fields, then the standard deviation of a population in
the second repetition fields, and so on.
