What is the mean of the numbers 6, 8, 3, and 7?

  1. 8

  2. 7

  3. 4

  4. 6

The correct answer is: 7

The mean, also known as the average, is calculated by adding up all the numbers and dividing the sum by the total number of values. In this case, adding 6 + 8 + 3 + 7 gives us 24. Since there are four numbers, we divide 24 by 4 to get the mean of 6. However, options A, C, and D are incorrect because they are either one value lower or higher than the correct mean of 7. Therefore, option B is the correct answer.
