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.

Answer:

12

Explanation:

To find mean, first add all the numbers in the data set.

12+15+10+11=48

Then divide the result by the amount of data in the data set.

Here, there are 4 numbers, which mean 4 pieces of data.

Which means you must divide 48 by 4.

48/4=12

therefore the mean is 12

Hope this helped!
