To find the median in a group of eight numbers, you should use the method outlined in your second option: **Average the numbers in the fourth and fifth positions.**
Here’s a step-by-step guide on how to find the median for a set of eight numbers:
1. **Arrange the numbers in ascending order** (from smallest to largest).
2. Since you have an even number of data points (eight), the median will be the average of the two middle numbers. In this case, those are the fourth and fifth numbers in the ordered list.
3. **Calculate the average of those two middle numbers**: (4th number + 5th number) / 2.
This method accurately identifies the median, which is defined as the value with an equal number of data points below and above it.
