Take your dice scores and find the mean. Next subtract the mean from each score to find the deviation score. Now, square each deviation score and add them all up.

**HINT:** A spreadsheet would be very helpful here and you can download one if you have access to Excel 3.0 or some other compatible program.

Once you have squared all of the deviation scores and added them all up, divide the sum by the number of scores. This will give you a measure known as the variance.

**Take a look at these sample scores:**

Now, look at a graphic representation of variance.
