# scipy.stats.fligner

`scipy.stats.``fligner`(*args, **kwds)

  Perform Fligner’s test for equal variances.

  Fligner’s test tests the null hypothesis that all input samples are from populations with equal variances. Fligner’s test is non-parametric in contrast to Bartlett’s test `bartlett` and Levene’s test `levene`.

  Parameters: | sample1, sample2, ... : array_like Arrays of sample data. Need not be the same length. center : {‘mean’, ‘median’, ‘trimmed’}, optional Keyword argument controlling which function of the data is used in computing the test statistic. The default is ‘median’. proportiontocut : float, optional When center is ‘trimmed’, this gives the proportion of data points to cut from each end. (See `scipy.stats.trim_mean`.) Default is 0.05.
  Returns: | Xsq : float The test statistic. p-value : float The p-value for the hypothesis test.

  Notes

  As with Levene’s test there are three variants of Fligner’s test that differ by the measure of central tendency used in the test. See `levene` for more information.
