# scipy.stats.trim1

`scipy.stats.``trim1`(a, proportiontocut, tail='right', axis=0)

  Slices off a proportion from ONE end of the passed array distribution.

  If proportiontocut = 0.1, slices off ‘leftmost’ or ‘rightmost’ 10% of scores. The lowest or highest values are trimmed (depending on the tail). Slices off less if proportion results in a non-integer slice index (i.e., conservatively slices off proportiontocut ).

  Parameters: | a : array_like Input array proportiontocut : float Fraction to cut off of ‘left’ or ‘right’ of distribution tail : {‘left’, ‘right’}, optional Defaults to ‘right’. axis : int or None, optional Axis along which to trim data. Default is 0. If None, compute over the whole array a.
  Returns: | trim1 : ndarray Trimmed version of array a. The order of the trimmed content is undefined.
