Skewness, Basic Statistics

Skewness

It is the comparison of the mean, median and mode can reveal information about the characteristics of skewness.

Definition

The distribution of the data is skewed if the data is not symmetric and  it extends more to one  side than the other. (A distribution of data is symmetric if the left half of its  histogram is roughly the mirror image of its right half.)

Type of skewness

  • Skewed to the left (Negatively Skewed):

The mean and median both lies to the left of the mode.

 

  • Symmetric (which is Zero Skewness):

The median, mean  and mode remains the same.

 

  • Skewed towards the right (Positively Skewed):

The mean and median both lies to the right of the mode.
