Statistics QUESTION #1977

In Bowley's coefficient of skewness defined as $S_k = \dfrac{Q_3 + Q_1 - 2Q_2}{Q_3 - Q_1}$, the value lies in the range:

0 to 1
$-1$ to $+1$✔️
$-3$ to $+3$
$-\infty$ to $+\infty$

Correct Answer Logic:

Bowley's coefficient of skewness is bounded between $-1$ and $+1$ because the numerator $Q_3 + Q_1 - 2Q_2$ can never exceed the denominator $Q_3 - Q_1$ in absolute value, since $Q_2$ always lies between $Q_1$ and $Q_3$.
