Answer:
12
Step-by-step 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!
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.
