To find the median in a data sample with an even number of values, you should **find the two middle values and average them**.
Here's a brief summary of the steps to determine the median in such a case:
1. **Sort the data** in ascending order.
2. Identify the two middle values (for a dataset with an even number of values, these will be the values at positions \(n/2\) and \(n/2 + 1\), where \(n\) is the total number of values).
3. Calculate the median by averaging these two middle values.
So, the correct option is: **Find the two middle values and average them.**
