def studentized_diff_of_means(data_1, data_2):
    """
    Studentized difference in means of two arrays.

    Parameters
    ----------
    data_1 : array_like
        One-dimensional array of data.
    data_2 : array_like
        One-dimensional array of data.

    Returns
    -------
    output : float
        Studentized difference of means.

    Notes
    -----
    .. If the variance of both `data_1` and `data_2` is zero, returns
       np.nan.
