Central tendency relates to the way in which quantitative
data tend to cluster around some value. Central tendency has three measures,
which is any of a number of ways of specifying central value. The mean is one
of the three measures of central tendency, which is best measure when the
distribution of data is continuous and symmetrical. It is the ordinary average,
the sum of all the scores divided by the number of scores (Aron, Aron, &
Coups, 2009). Therefore to find the mean one can add six numbers then divided
by six, which represents the amount of numbers added. The median, an
alternative to the mean is another of three measures of central tendency, which
is the best measure when data is skewed.

To find the median one must line up all the scores from
lowest to highest, then add 1 to the number of scores and dividing by 2, and
count up to the middle score or scores (Aron, Aron, & Coups, 2009). The
mode is the last of the three measures of central tendency, which is the most
frequently occurring score.
