RUNNING_AVG
RUNNING_AVG(SUM([Hours Spent]))Syntax
RUNNING_AVG({aggregation method}(numerical expression))
A running avg is the average of a sequence of numbers which is updated each time a new number is added to the sequence with the following calculation ({Previous Value} - {Previous Value} / Count) + ({Current Value} / Count).
aggregation method: Any aggregation function SUM, MAX, COUNT and etc applied to numeric expression.
numerical expression: Basic arithmetic calculation created using the math operators +, -, *, /, numerical data fields and constants.
For example we have the data set below after applying aggregation COUNT([ID]) to income record set
| # | COUNT([ID]) |
|---|---|
| 1 | 5 |
| 2 | 35 |
| 3 | 25 |
Applying RUNNING_AVG(COUNT([ID])) will give the table below
| # | RUNNING_AVG(COUNT([ID])) |
|---|---|
| 1 | 5 |
| 2 | (5-5/2) + (35/2) = 20 |
| 3 | (20-20/3)+25/3 = 21.67 |
