MEAN
The MEAN function returns a numeric value that approximates the arithmetic average of its arguments.
The function type is numeric.
- argument-1
- Must be class numeric.
The returned value is the arithmetic mean of the argument-1 series. The returned value is defined as the sum of the argument-1 series divided by the number of occurrences referenced by argument-1.
The equivalent arithmetic expression shall be as follows:
- For one occurrence of argument-1,
(argument-1)
- For two occurrences of argument-1,
((argument-11 + argument-12) / 2 )
- For n occurrences of argument-1,
((argument-11 + argument-12 + ... + argument-1n) / n)
