Answer :

To find the median of the set of numbers {100, 102, 103, 106, 109}, follow these steps:

1. Order the Numbers: Ensure the numbers are in ascending order. In this case, they already are: 100, 102, 103, 106, 109.

2. Count the Numbers: Determine how many numbers are in the set. Here, there are 5 numbers.

3. Find the Middle Point: Since there are 5 numbers, which is an odd count, the median will be the middle number in the ordered set.

4. Locate the Median: The middle number is the 3rd number in the list (since 5 divided by 2, rounded up, is 3).

5. Identify the Median: The 3rd number is 103.

Thus, the median of this set of data is 103.
