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.

MIDRANGE actually = lowest + highest / 2
