First sort the numbers into ascending order (from least to greatest):
31,34,34,35,40,41,44,47,48,52

Sample Mean:

To find the mean, add up all of the numbers and divide the sum by the number of numbers (which in this case is 10).


So the mean is 40.6

----------------------------------------------------------------
Median:


To find the median, count off about 5 spaces (just take half of the size of the list, which is 10) from the beginning of the list until you hit the middle. Now count count off about 5 spaces from the end of the list until you hit the middle.
31, 34, 34, 35, , , 44, 47, 48, 52
Since the middle is in between the numbers 40 and 41, add them up and divide that sum by 2.


So the median is 40.5

----------------------------------------------------------------
Mode:

To find the mode, simply look for any repeating numbers. If there is one number that occurs more frequently than any other number, then that number is the mode.
Since 34 repeats itself 2 times (which is more frequent than any other number), the mode is 34


So the mode is 34
