### Example Question #491 : Data Analysis

Use the following data set to answer the question.

Find the median of the data set.

Explanation:

To find the median of a data set, we will first arrange the numbers in ascending order.  Ascending order means from smallest to largest.  Once we arrange them in ascending order, we will locate the number that is in the middle or center of the set.

So, given the set

we will first arrange them in ascending order.  We get

Now, we will locate the number in the middle or center of the set.  We can see that  is in the center.

Therefore, the median of the data set is .

### Example Question #94 : How To Find Median
