1. Mean = (sum of scores)/number of scores

To find median, arrange scores in order of value. The median is that point which defines the higher 50% from the lower 50%.

Midrange = highest score-lowest score/2

The most central of these three measures (value in between the other two) would be the best measure of central tendency.
