- statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. The skewness value can...- In mathematics, particularly in linear algebra, a skew-symmetric (or antisymmetric or antimetric) matrix is a square matrix whose ...
One popular measure of skewness is Pearson’s First Coefficient, which is the ratio of the difference between mean and mode to the standard deviation. If the data is positively skewed, the coefficient is positive; else it is negative for negatively skewed data. An example of positively skewed ...
We implemented the criterion of values for skewness and kurtosis between ±2 as recognized for relatively normal distributed variables. Since the data were not normally distributed, the Spearman correlation was run to calculate the relationship between personality traits, positive orientation, and the ...

The skewness and kurtosis values for IADL and social activities performance and meaning, as well as QOL at both T1 and T2, were close to or less than ± 1. Therefore, the distributions of the data variables were considered to be normal. Thus, Pearson product-moment correlation analysis ...
Living arrangements have impact on life satisfaction among older adults. However, the mechanism how it works has received less attention. This study aims to examine the mediating role of meaning in life and social support in the relationship between livi
Sometimes there isskewness, or a lack of symmetry, between what falls above and below the mean. Other times there are fat tails (excess kurtosis), makingtailevents more probable than the normal distribution would predict. What Are the Characteristics of a Bell Curve?
Mesokurtic is the distribution (frequency or graphical) whose kurtosis is similar to the kurtosis of the normally distributed data set.Kurtosis(Greek word meaning bulging) gives the measure of peakedness of a probability distribution of a random variable. It gives the measure of skewness of a dist...
,Statistics. a ratio associated with the probability of a sample, usually the ratio of the deviation from the mean to the standard deviation: The critical ratios were created by dividing the skewness by the standard error values for each variable. ...
