Answer 1

Answer:

Step-by-step explanation:

What is Pearson’s Coefficient of Skewness?

Karl Pearson developed two methods to find skewness in a sample.

   Pearson’s Coefficient of Skewness #1 uses the mode. The formula is:

   pearson skewness

   Where xbar = the mean, Mo = the mode and s = the standard deviation for the sample.

   See: Pearson Mode Skewness.

   Pearson’s Coefficient of Skewness #2 uses the median. The formula is:

   Pearson's Coefficient of Skewness

   Where xbar = the mean, Mo = the mode and s = the standard deviation for the sample.

   It is generally used when you don’t know the mode.
