Statistics QUESTION #1995

For a distribution where $Q_1 = 40$, $Q_2 = 60$, and $Q_3 = 80$, Bowley's coefficient of skewness $S_k = \dfrac{Q_3 + Q_1 - 2Q_2}{Q_3 - Q_1}$ equals:

0.5
1
−0.5

Correct Answer Logic:

Substituting: $S_k = \dfrac{80 + 40 - 2(60)}{80 - 40} = \dfrac{120 - 120}{40} = \dfrac{0}{40} = 0$. A value of zero indicates a perfectly symmetric distribution, since the median lies exactly midway between the two quartiles.
