If we have the data 5, 8, 15, 7, 10, 22, 3, 1, 15, 2 What is the median?

To find the median of this data set, follow these steps:

1. **Arrange the data in ascending order:**

   1, 2, 3, 5, 7, 8, 10, 15, 15, 22

2. **Count the total number of data points:**  
   There are 10 numbers.

3. **Identify the middle numbers:**  
   Since the number of data points is even, the median is the average of the two middle numbers. In this case, the two middle numbers are the 5th and 6th numbers in the ordered list.

4. **Locate the 5th and 6th numbers:**  
   The 5th number is **7** and the 6th number is **8**.

5. **Calculate the average of the two middle numbers:**

   \[
   \text{Median} = \frac{7 + 8}{2} = \frac{15}{2} = 7.5
   \]

Thus, the median is **7.5**.
