Example Question #114 : How To Find Median

Find the median of the following data set:

Possible Answers:

Correct answer:

Explanation:

The median of a data set is the number that appears in middle of center of the set when it is written in ascending order.  Given the data set

1, 3, 6, 4, 1, 6, 1, 7, 11

we will write it in ascending order.  We get

1, 1, 1, 3, 4, 6, 6, 7, 11

The number that appears in the middle or center is the number 4.  Therefore, the median is 4.

Example Question #115 : How To Find Median

To find the median of a data set, you arrange the numbers in ascending order and locate the number that is in the center.  So, given the data set

4, 2, 7, 8, 8, 2, 8, 10, 7

we will write it in ascending order, giving us

2, 2, 4, 7, 7, 8, 8, 8, 10

and locate the number in the center of the list.  In this case, the number 7 is in th emiddle of the list, so 7 is the median.
