Hello There!
Mean: Average of numbers in a set of data.
STEP 1: Add the numbers in the data set. In this case, we would add
12 + 15 + 17 + 16 + 10 = 70
STEP 2: Divide the sum by the number of digits you added. We would divide 70 "sum of numbers" by 5 "number of digits" and would get an answer of 14.
Median: The middle number when all the numbers are listed in order.
STEP 1: Put the numbers in order.
-Least To Greatest- 10-12-15-16-17
STEP 2: Cross out each number on the left and on the right until we come across one number in the middle. The number in the middle is 15 so our median is 15.
Mode: The number that occurs most often in a set of numbers.
There would be no mode for this set of numbers. This is because no numbers repeat in the set so there would be no mode.
