Measures of central tendency

In statistics, measures of central tendency are a group of mathematical technologies (ie, procedures or formulas) used for summarising data. These measures may also be known as averages, and typically refer to the following:

role name
The mid-range value in a distribution mid-range
The most typical or frequent value in a distribution mode
The value in the middle of the range once all values in the distribution are arranged in an ordinal manner median
The value which is the most equidistant to all other values in the distribution arithmetic mean

Although these measures of central tendency inform about the average value in a distribution of scores, more complete information about the distribution can be obtained by complimenting those with their corresponding measures of dispersion.
