Explanation / Answer

solution:-

The first quartile of the data set is 15.
Explanation:-
The first quartile (or lower quartile or 25th percentile)
is the median of the bottom half of the numbers. So, to find the first quartile,
we need to place the numbers in value order and find the bottom half.
4,6,14,16,25,27,28,36,38,45,46,48
So, the bottom half is
4,6,14,16,25,27

The median of these numbers is 15.

The third quartile of the data set is 41.5.
Explanation:-
The third quartile (or upper quartile or 75th percentile) is the median of the upper half of the numbers. So, to find the third quartile, we need to place the numbers in value order and find the upper half.
4,6,14,16,25,27,28,36,38,45,46,48

So, the upper half is

28,36,38,45,46,48

The median of these numbers is 41.5.
