stdDev

Calculates the simple 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. 

stdDev(dataset, columnIndex)

• Parameters

Dataset dataset - The dataset to search through.

Integer columnIndex - The index of the column to search through. Must be a column index of the provided dataset.

• Returns

Integer/Float - The standard deviation of the values in that column.

stdDev(dataset, columnName)

• Parameters

Dataset dataset - The dataset to search through.

String columnName - The name of the column to search through. Must match a column name in the provided dataset.

• Returns

Integer/Float - The standard deviation of the values in that column.

stdDev(value, [value, ...])

• Parameters

Integer/Float value - A number. Can be as many values as needed. Can be either a float or an integer.

• Returns

Integer/Float - The standard deviation of the values in the list of values.

stdDev(sequence)

• Parameters

Sequence sequence - A list, tuple, array, or set of numerical values.
