StatAverageDeviation (Function)

In french: StatEcartMoyen

Calculates the average deviation of values in relation to their arithmetic mean.

Remark: The average deviation gives the dispersion in a set of values.

Example

See additional examples

// Calculate the average deviation of the elements in row 1 of a matrix
ResAverageDeviation = StatAverageDeviation("MyMatrix", 1, False)

Syntax

<Result> = StatAverageDeviation(<Matrix> [, <Row/Column number> [, <Row/Column>]])

<Result>: Real

Average deviation of values,
0 if the average deviation is null.

<Matrix>: Character string (with quotes)

Name of the matrix containing the data, defined by MatCreate.

<Row/Column number>: Optional integer

Number of the row or column containing the data (1 by default).

<Row/Column>: Optional boolean

True (by default) if the series of values corresponds to a matrix column,
False if the series of values corresponds to a matrix row.

Remarks

Number of elements found in a matrix row or in a matrix column

The number of elements found in a matrix row or in a matrix column is taken as a reference. This number of elements corresponds to:

the total number of matrix rows, returned by MatNbLine (if the calculation is performed on a column),
the total number of matrix columns, returned by MatNbColumn (if the calculation is performed on a row).

If the series contain less elements than the matrix, the missing values are automatically filled with 0. These values are taken into account during the calculations.

Managing errors

Caution: StatAverageDeviation returns no error code. To find out whether errors have been generating when calculating the average deviation, use StatError. To find out the error details, use ErrorInfo associated with the errMessage constant.
