Compute the Karl Pearson Coefficient of Skewness for the data given here 27, 3, 28, 40, 28, 30, 35, 27, 25, 27?
Show answer & explanation
Correct answer: D
Explanation
Skewness = (Mean − Mode) ÷ Standard Deviation
27, 3, 28, 40, 28, 30, 35, 27, 25, 27
Mode = 27
Sum = 270
Mean = 270 ÷ 10 = 27
Skewness = (27 − 27) ÷ Standard Deviation
= 0
