The median is:  

Example Question #342 : Algebra Ii

Solve for the median:  

Possible Answers:

Correct answer:

Explanation:

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

Negative half is less than negative two-fifth.

Since this is an even number set of numbers, the median is the average of the middle two numbers.

The median is:  

Example Question #343 : Algebra Ii

Solve for the median:  

Possible Answers:

 

Correct answer:

 

Explanation:

The median of an even number set is the average of the center two numbers in a chronological ordered set from least to greatest.

To arrange the data set, we will need to compare numerators of the similar denominator.

Find the least common denominator.  The least common denominator is  since it is the minimum number divisible by all of the existing denominators.

Convert all fractions to the common denominator.

The data set becomes:  

We can now see that the middle two numbers are:  

Average these two numbers.

The answer is:  

Example Question #344 : Algebra Ii

Solve for the median:  

Possible Answers:

Correct answer:

Explanation:

In order to solve for the median, we will need to rearrange the data set in chronological order from least to greatest.

In an even set of data, the median is the average of the central two numbers.

Average the center two numbers.

The median is:  

Example Question #345 : Algebra Ii

Solve for the median:  

Possible Answers:

Correct answer:

Explanation:

The numbers not in chronological order.

Change the fractions and the integer to a common denominator.  The common denominator of the fractions is  since this is the least number that is divisible by each of the denominators given.

Convert the fractions.

The median of an even data set is the mean of the center two numbers in a chronological ordered data set from least to greatest.  

The central numbers are  and .

Average these numbers.

The answer is:  

Example Question #41 : Median

Solve for the median:  

Possible Answers:

Correct answer:

Explanation:

Reorder the data set from least to greatest.

The median in an odd set of numbers will the average of the two central numbers given.

Average the two center numbers.

The answer is:  

Example Question #42 : Median

Determine the median:  

Possible Answers:

Correct answer:

Explanation:

The data set provided is not in chronological order.

Reorder the set from least to greatest.

Since this an even numbered data set, we will need need to average the two center numbers to find the median.

The median is:
