What is the mean of the data set? 12,15,10,11

First, you want to add up all the numbers.
So, 12+15+10+11.

Then, we get a sum of 48. Now we want to take the total number, of numbers and divide 48, by that.
So, 48/4.

I got, 12.
So therefore, 12 will be your final answer.

To find the mean, you add all the numbers given (12, 15, 10, and 11) and then divide by the number of values in the set (in this case, 4). This is the same as finding an average. To do this, you add 12 + 15 + 10 + 11 = 48. Since you have 4 numbers, you do 48 ÷ 4, which equals 12. Therefore, the mean is 12.
