Skewness Value Meaning. Hence the mean value is less than the median and moves towards the left and the mode occurs at the highest frequency of the distribution. So towards the right of the graph the scores become more positive.
In other words skewness tells you the amount and direction of skew departure from horizontal symmetry. The skewness is a measure of the asymmetry of the probability distribution assuming a unimodal distribution and is given by the third standardized moment. In probability theory and statistics skewness is a measure of the asymmetry of the probability distribution of a real valued random variable about its mean.
We can say that the skewness indicates how much our underlying distribution deviates from the normal distribution since the normal distribution has skewness 0.
Therefore right skewness is positive skewness which means skewness 0. In other words skewness tells you the amount and direction of skew departure from horizontal symmetry. In statistics skewness is a measure of the asymmetry of the probability distribution of a random variable about its mean. In probability theory and statistics skewness is a measure of the asymmetry of the probability distribution of a real valued random variable about its mean.
