What is data skewness?
When most of the values are skewed to the left or right side from the median, then the data is called skewed.
Data can be in any of the following shapes;
 Symmetric: Mean, median and mode are at the same point.
 Positively skewed: When most of the values are to the left from the median.
 Negatively skewed: When most of the values are to the right from the median.
