Answer

Given

Arrange data in order:

11,13,14,20,20,22,22,24,25,27,29,29.

The bottom half:

11,13,14,20,20,22.

The upper half:

22,24,25,27,29,29.

_______________________

The first Quartile:

The median of the bottom half of the numbers,

=

_______________________

The Third Quartile:

The median of the Upper half of the numbers,

=

________________________

The second Quartile:

11,13,14,20,20,22,22,24,25,27,29,29.

a middle number of the sorted data:

=22
