Aggregates / stdDev

stdDev(dataset, column OR number, number...)

Calculates the standard deviation of the values in the given column of the given dataset, or the standard deviation for a series of numbers specified as arguments. When looking up the standard deviation in a dataset, the column may be specified as an index or as a column name. Any null values in the column are ignored. If there are no rows in the dataset, zero is returned.

 

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

 

stdDev({Root Container.Table.data}"Weight")

... would return 4.00532
