What is the mean of the numbers 3, 7, 7, and 10?

Explanation:
The mean is found by adding all the numbers together and dividing by how many numbers there are. Add them up: 3 plus 7 plus 7 plus 10 equals 27. There are 4 numbers, so you divide 27 by 4, which gives 6.75. So the mean is 6.75. If the mean were 6.5, the total would be 6.5 times 4 = 26, not 27. If it were 7, the total would be 28, not 27. If it were 6.25, the total would be 25, not 27.
