Find the mode of the following values: 102, 107, 105, 101, 105, 104, 104, 106, 109, 108, 108, 106, 104

To find the mode of a set of numbers, you need to identify the number that appears most frequently in the set.

Here are the steps:

1. List the numbers in ascending order: 101, 102, 104, 104, 104, 105, 105, 106, 106, 107, 108, 108, 109
2. Count how many times each number appears:
   • 101 appears 1 time
   • 102 appears 1 time
   • 104 appears 3 times
   • 105 appears 2 times
   • 106 appears 2 times
   • 107 appears 1 time
   • 108 appears 2 times
   • 109 appears 1 time
3. Identify the number that appears most frequently: 104 appears 3 times, which is more than any other number.

So, the mode of the given set of numbers is 104.
