    Mean:  Find the sum of all the numbers and divide by the number of items.  Think of Mean as Average.

    Median:  Arrange the numbers is ascending order beginning with the lowest number and end with the highest.  Find the number which is in the middle.  In this case you have 10 numbers. What 2 numbers lie in the middle (you should have 4 numbers on both the left & right of these numbers).  Take the average of the middle 2 numbers.

    Mode:  Find numbers which appear more than once.  

    Modality:  Take the highest and lowest number and find their average.
