The right and the left side may not be mirror images. Skewness measures this extent of asymmetry. If the data is positively skewed then it will have a much longer right tail than the left tail. In this case, mean and median will be greater than mode. In most of the cases, mean will...

Skewed distributions occur when one tail is longer than the other. Skewness defines the asymmetry of a distribution.
You might want to calculate the skewness of a distribution to:Describe the distribution of a variable alongside other descriptive statistics Determine if a variable is normally distributed. A normal distribution has zero skew and is an assumption of many statistical procedures....

The normal distribution is the easiest distribution to work with in order to gain an understanding about statistics. Real life distributions are usually skewed. Too much skewness, and many statistical techniques don’t work. As a result, advanced mathematical techniques including logarithms and quantile...
Asymmetrical distribution is a situation in which the values of variables occur at irregular frequencies and the mean, median, and mode occur at different points. An asymmetric distribution exhibitsskewness. In contrast, a Gaussian ornormal distribution, when depicted on a graph, is shaped like a ...
similar to a histogram orprobability distributionfunction. Dot plots allow a quick visual analysis of the data to detect the central tendency, dispersion, skewness, and modality of the data.
