Example Question #1751 : Algebra 1

Find the median of the following set of numbers:

1,1,3,7,7,8,9,12,15

Possible Answers:

Correct answer:

Explanation:

To find median, you must remember that the median is the middle number in your set. This means you need to count equally from the left and the right to find the middle number. Since there are 9 numbers in this set, you must find the 5th number from either direction.

Thus, you answer is 7.

Example Question #123 : How To Find Median

Possible Answers:

Correct answer:

Explanation:

Resort the dataset into chronological order from least to greatest.

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

Average the two numbers.

The median is:  

Example Question #1752 : Algebra 1

Find the median of the data set

10, 9, 11, 10, 8, 4, 10, 7, 8

Possible Answers:

Correct answer:

Explanation:

To find the median of a data set, we must write the values of the data set in ascending order then find the center or middle number within the set.  Given the set

10, 9, 11, 10, 8, 4, 10, 7, 8

we will write this set in ascending order.  We get

4, 7, 8, 8, 9, 10, 10, 10, 11

Now, we locate the value that is in the center or middle of the set.  That value is 9.  Therefore, the median of this set of data is 9.

Example Question #1753 : Algebra 1

Find the median of the following data set:

13, 4, 6, 3, 9, 3, 11, 11, 3

Possible Answers:

Correct answer:

Explanation:

To find the median, we must write the data set in ascending order (smallest to largest) and locate the number that is in the middle or the center.  Given the set

13, 4, 6, 3, 9, 3, 11, 11, 3

we will write it in ascending order.  We get

3, 3, 3, 4, 6, 9, 11, 11, 13

We locate the number that is in the middle or center of the set.  In this case, that number is 6.  Therefore, the median is 6.

Example Question #1754 : Algebra 1

Find the median of the following data set:

15, 9, 11, 14, 12, 11, 13, 11, 12

Possible Answers:

Correct answer:

Explanation:

To find the median of the data set, we will first arrange the numbers in ascending order (from smallest to largest), then locate the number in the middle or center of the set. 

 

Given the set

15, 9, 11, 14, 12, 11, 13, 11, 12

we will arrange them in ascending order.  We get

9, 11, 11, 11, 12, 12, 13, 14, 15

 

Now, we will locate the number in the middle or center of the set.  That number is 12.  

 

Therefore, the median of the data set is 12.
