• stdev(n: number, p: number): number

• Returns the standard deviation of a binomial distribution.

  Notes

  • If provided a number of trials n which is not a nonnegative integer, the function returns NaN.
  • If p < 0 or p > 1, the function returns NaN.

  Parameters

  • n: number

    number of trials

  • p: number

    success probability

  Returns number

  standard deviation

  Example

  var v = stdev( 100, 0.1 );
  // returns 3.0

  Example

  var v = stdev( 20, 0.5 );
  // returns ~2.236

  Example

  var v = stdev( 10.3, 0.5 );
  // returns NaN

  Example

  var v = stdev( 20, 1.1 );
  // returns NaN

  Example

  var v = stdev( 20, NaN );
  // returns NaN
