When the smaller values tend to be farther away from the mean than the larger values, one has a skew distribution to the left (i.e. there is negative skewness), one may for example select the ''square-normal distribution'' (i.e. the normal distribution applied to the square of the data values){{Citationneeded|reason<ref name=Non-standard"skew"> termLeft and(negatively) specificskewed claim;frequency notehistograms thatcan thebe fitted to square ofNormal aor realmirrored randomGumbel variableprobability cannotfunctions. actuallyOn beline: normal|date=January[https://www.researchgate.net/publication/338633570_Left_negatively_skewed_frequency_histograms_can_be_fitted_to_square_Normal_or_mirrored_Gumbel_probability_functions] 2020}}</ref>, the inverted (mirrored) Gumbel distribution <ref name=skew/>, the [[Dagum distribution]] (mirrored Burr distribution), or the [[Gompertz distribution]], which is bounded to the left.
