Question 1090833: Show the mean, mode, median and range for this set of data ( 2,4,9,3,5,2,4,2,5)

You can put this solution on YOUR website! The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.
mean | {2, 4, 9, 3, 5, 2, 4, 2, 5} is 
The "mode" is the value that occurs most often. If no number in the list is repeated, then there is no mode for the list.
commonest element, mode | {  , 4, 9, 3, 5, , 4, , 5}; so, mode is 
The "median" is the "middle" value in the list of numbers. To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median.
median | {2, 4, 9, 3, 5, 2, 4, 2, 5} =>
{2,2, 2,3, ,4, 5, 5,9}
median | {2, 4, 9, 3, 5, 2, 4, 2, 5} is
