Question

How do you calculate Karl Pearson coefficient of skewness?

Answer 1

Answer:

Step 1: Subtract the median from the mean: 70.5 – 80 = -9.5. Step 2: Divide by the standard deviation: -28.5 / 19.33 = -1.47. Caution: Pearson's first coefficient of skewness uses the mode.

Answer 2

Answer:

In this Karl Pearson formula,

x = (X - X_ )

y = (X - Y_ )

r=NΣdx. dy−(Σdx)(Σdy)√NΣdx2−(Σdx)2√NΣdy2−(Σdy)2.
