     * Estimates the standard deviation of a population based on a sample by using the numbers in a
     * column of a list or database that match conditions that you specify.
     *
     * Excel Function:
     *        DSTDEV(database,field,criteria)
     *
     * @param mixed[] $database The range of cells that makes up the list or database.
     *                                        A database is a list of related data in which rows of related
     *                                        information are records, and columns of data are fields. The
     *                                        first row of the list contains labels for each column.
     * @param int|string $field Indicates which column is used in the function. Enter the
     *                                        column label enclosed between double quotation marks, such as
     *                                        "Age" or "Yield," or a number (without quotation marks) that
     *                                        represents the position of the column within the list: 1 for
     *                                        the first column, 2 for the second column, and so on.
     * @param mixed[] $criteria The range of cells that contains the conditions you specify.
     *                                        You can use any range for the criteria argument, as long as it
     *                                        includes at least one column label and at least one cell below
     *                                        the column label in which you specify a condition for the
     *                                        column.
