Examples
For example, suppose you had a table with this dataset in it:
| ProductCode | Quantity | Weight |
|---|---|---|
| BAN_002 | 380 | 3.243 |
| BAN_010 | 120 | 9.928 |
| APL_000 | 125 | 1.287 |
| FWL_220 | 322 | 7.889 |
median({Root Container.Table.data}, "Weight") //... would return 5.566
median(1,2,3,3,10) //... would return 3
