# scipy.stats.mstats.idealfourths

`scipy.stats.mstats.``idealfourths`(data, axis=None)

  Returns an estimate of the lower and upper quartiles.

  Uses the ideal fourths algorithm.

  Parameters: | data : array_like Input array. axis : int, optional Axis along which the quartiles are estimated. If None, the arrays are flattened.
  Returns: | idealfourths : {list of floats, masked array} Returns the two internal values that divide data into four parts using the ideal fourths algorithm either along the flattened array (if axis is None) or along axis of data.
