    Computes the spread of the data values in a sequence.

    datatype_icon

    x

    Data set.

    datatype_icon

    type

    Type of spread to compute.

    Name Value Description
    standard deviation 0

    Computes the standard deviation, or the square root of the variance, of x. The standard deviation is the most common measure of spread in a data set.

    range 1

    Computes the range, or the difference in the minimum and maximum values, of x.

    mean absolute deviation 2

    Computes the mean of the absolute value of the deviation of x from its mean.

    interquartile rank 3

    Computes the difference between the 25th and 75th percentile of x. This measure of spread therefore is more resistive to outliers than the other measures.

    Default: standard deviation

    datatype_icon

    error in

    Error conditions that occur before this node runs.

    The node responds to this input according to standard error behavior.

    Standard Error Behavior

    Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Default: No error

    datatype_icon

    spread value

    Spread of the input data set.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.
