Inputs/Outputs

  • c1ddbl.png X —

    X is the input sequence.

  • cenum.png Weighting (Sample) —

    Weighting determines whether to calculate the population or the sample standard deviation and variance.

    0
    Sample
    (default)
    1
    Population
  • idbl.png mean —

    mean is the mean, or average, of the values in the input sequence X.

  • idbl.png standard deviation —

    standard deviation is the standard deviation calculated from the values in the input sequence X.

  • idbl.png variance —

    variance is the calculated variance of the values in the input sequence X.

    • The VI calculates the output values using the following equations.

    where µ is mean and n is the number of elements in X.

    standard deviation = σ

    where σ² is variance, µ is mean, and w is n when Weighting is set to Population and (n – 1) when Weighting is set to Sample.
