To find the mode of a set of numbers, you want to identify the number that appears most frequently. In our case, we have the following numbers: 19, 1, 17, 19, 3, 20, 5, and 2.
Let’s analyze the frequency of each number:
- 19 appears twice
- 1 appears once
- 17 appears once
- 3 appears once
- 20 appears once
- 5 appears once
- 2 appears once
From this count, we can observe that the number 19 is the only number that occurs more than once. Therefore, it is the mode of this set of numbers.
In summary, the mode of the numbers 19, 1, 17, 19, 3, 20, 5, and 2 is 19.
