Quartile deviation = ?Select one:a.Q_3 - Q_1b.Q_1 - Q_3c.(Q_3 - Q_1)/2d.(Q_3 - Q_1)*2
Question
Quartile deviation = ?Select one:a.Q_3 - Q_1b.Q_1 - Q_3c.(Q_3 - Q_1)/2d.(Q_3 - Q_1)*2
Solution
The correct answer is c. Quartile deviation is calculated as (Q_3 - Q_1)/2. This is also known as the semi-interquartile range. It is a measure of statistical dispersion, being equal to half the difference between the upper and lower quartiles.
