Question: Find the mode of the following set of numbers: 10, 12, 10, 15, 10, 20, 15, 15.
Options:
Correct Answer: 15
Solution:
The number 10 appears 3 times and 15 appears 3 times. Since both have the highest frequency, the mode is 10 and 15 (bimodal). However, if only one mode is required, we can take the first one, which is 10.
