# scipy.stats.bartlett

`scipy.stats.``bartlett`(*args)

  Perform Bartlett’s test for equal variances

  Bartlett’s test tests the null hypothesis that all input samples are from populations with equal variances. For samples from significantly non-normal populations, Levene’s test `levene` is more robust.

  Parameters: | sample1, sample2,... : array_like arrays of sample data. May be different lengths.
  Returns: | statistic : float The test statistic. pvalue : float The p-value of the test.
