Measures of Skewness - Bowley’s Coefficient of Skewness

For a distribution Q₃ – Q₂ = 40, Q₂ – Q₁ = 60. Find Bowley’s coefficient of skewness Sk_b.

Find Sk_b for the following set of observations:
18, 27, 10, 25, 31, 13, 28.

For a frequency distribution Q₃ – Q₂ = 90 And Q₂ – Q₁ = 120, find Sk_b.

Calculate Sk_b for the following set of observations of yield of wheat in kg from 13 plots:
4.6, 3.5, 4.8, 5.1, 4.7, 5.5, 4.7, 3.6, 4.2, 3.5, 3.6, 5.2

For a data set, sum of upper and lower quartiles is 100, difference between upper and lower quartiles is 40 and median is 30. Find the coefficient of skewness.

Calculate Bowley’s coefficient of skewness Sk_b from the following data:

Obtain the coefficient of skewness by formula and comment on nature of the distribution.

For a distribution, Q₁ = 25, Q₂ = 35 and Q₃ = 50. Find Bowley’s coefficient of skewness Sk_b.
