Description
Returns the variance of a sample represented by a series of non-blank values. The
variance of a distribution is a measure of how spread out the distribution is. Use this
function on any of the following fields:
• 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...).
