Arguments
| Name | Description | Range | Type | Default | Required |

| data | data to find the stddev | (-∞, ∞) | real | yes | |
| flag | indicates how stddev normalizes | [0, 1]† | integer | 0 | no |
| † When flag equals 0, the stddev normalizes by N-1, where N is the length of the data sequence. Otherwise, stddev normalizes by N | |||||
