Left Skewed DistributionValuesFrequency No Skew Distribution A no skew distribution, also known as a symmetrical distribution, has tails that extend towards both the lower and higher values evenly. The majority of the data is concentrated around the mean. ...
, the sample period stocks average excess return was -1.73, the market average excess return rate of -1.60. Skewness skewness of the x and y is less than zero, mild left-skewed. The peak of the two is less than 3, a low peak. Skewness and kurtosis and are not a normal distribution...

That is, there are too many rare species to fit a lognormal distribution. I propose that this log-left-skew might be a sampling artefact. Monte Carlo simulations show that taking progressively larger samples from a log-unskewed distribution (such as the lognormal) causes log-skew to decrease...

(M± SEM amplitude: normal viewing = 4.77° ± 0.25; left offset window = 3.69° ± 0.14; right offset window = 3.81° ± 0.22). The distribution of amplitudes was positively skewed, as observed in previous studies (Foulsham et al., 2011,Tatler and Vincent, 2008). In normal viewing, ...
Negative, or left-skewed refers to a longer or fatter tail on the left side of the distribution, while positive, or right-skewed, refers to a longer or fatter tail on the right. These two skews show the direction or weight of the distribution. The three probability distributions below are ...
