std method

double std(List<double> data)

Implementation

double std(List<double> data) {
  var stdSum = 0.0;
  final dataAv = data.reduce((l, r) => l + r) / data.length;
  final length = data.length;
  for (final sample in data) {
    stdSum += pow(sample - dataAv, 2);
  }
  final std = sqrt(stdSum / length);
  return std;
}
