The value that occurs most frequently in a set of results.
Revise: Descriptive StatisticsThe mean, median and mode are measures of central tendency: they describe the centre or a typical value of a set of results. The range describes something different — how spread out the results are. It is a measure of dispersion.
The mode is the most frequent value, not the number of times it appears. Keep repeated scores when calculating the mean.
State that the mean, median and mode are equal in a perfect normal distribution, not merely that they are all averages.
Equal mean, median and mode are consistent with a normal distribution, but do not by themselves prove that a dataset has a bell-shaped distribution.

Revise: Descriptive StatisticsThe mean, median and mode each do this differently. Dispersion describes how spread out the scores are. Using both gives a more useful summary than an average alone.
