The numbers will need to be rewritten in order from least to greatest.

$\displaystyle [-3,9,-2,-1,4,-3] \rightarrow [-3,-3,-2,-1,4,9]$

The median of an even set of numbers is the average of the center two numbers.

$\displaystyle \frac{-2-1}{2} = \frac{-3}{2}$

The answer is:  $\displaystyle -\frac{3}{2}$

Reorganize the numbers from least to greatest.

$\displaystyle [3,9,-4,-18,5,7]\rightarrow[-18,4,3,5,7,9]$

Since there is even amount of numbers provided in the set, the median is the average of the center two numbers.

Average the two numbers.

$\displaystyle \frac{3+5}{2} = \frac{8}{2}=4$

The answer is:  $\displaystyle 4$

Reorganize the numbers from least to greatest.

$\displaystyle [ -3,9,24,-1,-16,33]\rightarrow [-16,-3,-1,9,24,33]$

The median for an even amount of numbers in the data set is the average of the two central numbers.

Average the two numbers.

$\displaystyle \frac{-1+9}{2} = \frac{8}{2} =4$

The answer is:  $\displaystyle 4$

Reorder the numbers from least to greatest.

$\displaystyle [-3,-9,27,18]\rightarrow [ -9,-3,18,27]$

The median of an even set of data is the average of the center two numbers in a chronological ordered set of numbers.

Average the two numbers.

$\displaystyle \frac{-3+18}{2} = \frac{15}{2}$

The answer is:  $\displaystyle \frac{15}{2}$

The median is defined as the central number of a given set of numbers.  We have two real numbers and two irrational numbers.  However, notice that there is an imaginary term given in the data set.  

$\displaystyle i=\sqrt{-1}$

This value is undefined and is not a real number.  We cannot reorder the data set in chronological order and the median is unknown.

The answer is:  $\displaystyle \textup{Cannot be determined.}$

The median of a set of even numbers is the average of the central two numbers in a least to greatest ordered set.

Arrange the numbers from least to greatest.

$\displaystyle [9,-3,28,0]\rightarrow [ -3,0,9,28]$

Average the center two numbers.

The answer is:  $\displaystyle \frac{9}{2}$

Reorganize the data set in chronological order.

$\displaystyle [0,-9,8,-7,3,39]\rightarrow [-9,-7,0,3,8,39]$

The median is the average of the 2 central numbers in an even set of data.

Average the two numbers.

$\displaystyle \frac{0+3}{2} = \frac{3}{2}$

The answer is:  $\displaystyle \frac{3}{2}$

Rearrange the numbers from least to greatest.

$\displaystyle [-5,-8,36,52]\rightarrow [-8,-5,36,52]$

The median of an even set of numbers is the average of the center two numbers in the data set.

Average the two numbers.

$\displaystyle \frac{-5+36}{2}= \frac{31}{2}$

The answer is:  $\displaystyle \frac{31}{2}$

In order to determine the median, first we will need to rearrange the numbers from least to greatest.

$\displaystyle [-2,-8,16,-32,13,7]\rightarrow [-32,-8,-2,7,13,16]$

The median of an even numbered set of numbers is the average of the central two numbers in the data set.

Average the two numbers.

$\displaystyle \frac{-2+7}{2} = \frac{5}{2}$

The median is:  $\displaystyle \frac{5}{2}$

Reorganize the data set in chronological order from least to greatest.

$\displaystyle [-4,3,-2,-8,0,1]\rightarrow [-8,-4,-2,0,1,3]$

The median of an even set of data is the average of the two central numbers of an ordered set.

Average the two numbers.

$\displaystyle \frac{(-2)+0}{2} = -1$

The answer is:  $\displaystyle -1$
