Let's look at the dice game again. Pool all of the scores in your class so we can compare them. Here is a sample set of scores (you may download this set of scores as a spreadsheet if you have access to Excel):

**15, 11, 19, 13, 16, 16, 17, 14, 22, 15, 16, 19, 18, 12, 16, 15, 18, 20, 23, 18, 17, 17, 17, 16**

Now, then put them in order (lowest to highest or highest to lowest, it doesn't matter).

**11, 12, 13, 14, 15, 15, 15, 16, 16, 16, 16, 16, 17, 17, 17, 17, 18, 18, 18, 19, 19, 22, 20, 23**

Find the average: **Average = (sum of all scores) / (number of scores)**

The average of our sample set of scores is 16.667. So, using this measure, anyone who scored above a 16.667 did well and anyone below 16.667 should try rolling again. "Luck be a lady tonight!"

Please continue on to learn about the median. If you have already studied the median, you may go on to the section on central tendency.
