Question

What is the mean absolute deviation of 1,1,4,8,9,3,8?

Answer 1

ok here is what you are going to do, you are going to average. Saying the mean is basically saying the average of numbers. You have 3 things with numbers. Mean= average
Median= middle number in a list of numbers
Mode= number that is repeated the most times

In this case we are discussing the mean. 1+1+4+8+9+3+8=34 ok now that we have that we are going to divide to get the average. We count the numbers and get 7 numbers in the list. So we divide 34/7=rounding to the nearest hundredths 4.86
