The term "measures of central tendency" is a fancy name
for mean, median and mode (Schultzkie, 2007).
Mean: Average. The sum of a set of data divided by
the number of data. (Do not round your answer unless
directed to do so.)
Median: The middle value or the mean of the middle two
values, when the data is arranged in numerical order.
Mode: The value ( number) that appears the most. It is
possible to have more than one mode, and it is possible
to have no mode. If there is no mode-write "no mode,"
do not write zero (0) .
