$Q_{1} = 15$ $Q_1=15$

Explanation:

$arrange the data set in ascending order$ $"arrange the data set in ascending order"$

$11 x 12 x 15 x 16 x 17 x 19 x 22 x 24 x 29 x 33 x 38$ $11color(white)(x)12color(white)(x)color(magenta)(15)color(white)(x)16color(white)(x)17color(white)(x)color(red)(19)color(white)(x)22color(white)(x)24color(white)(x)29color(white)(x)33color(white)(x)38$

$the median Q_{2} is the middle value of the$ $"the median "color(red)(Q_2)" is the middle value of the"$
$data set in ascending order$ $"data set in ascending order"$

$\Rightarrow Q_{2} = 19$ $rArrcolor(red)(Q_2)=19$

$the lower quartile Q_{1} is the middle value of the$ $"the lower quartile "color(magenta)(Q_1)" is the middle value of the"$
$data set to the left of the median$ $"data set to the left of the median"$

$\Rightarrow Q_{1} = 15$ $rArrcolor(magenta)(Q_1)=15$
