                    Median, Mean, and Mode

 
The median, mean, and mode are important statistical
concepts.  They are measures of central tendency.   What is
the median?  What is the mean?  What is the mode?

Median Definition:

The median is the value that is at the midpoint of a
distribution of scores in which the scores have been placed
in order from lowest to highest.

Median Example:

  
For example, imagine in a study there are 11 participants
with the following scores:

2, 5, 7, 7, 7, 8, 8, 9, 9, 10, 10,

The median of the 11 scores above is 8.

Mean Definition:

 
The mean is an average that is calculated by adding all the
scores and dividing the total by the number of scores.

Mean Example:

  
For example, imagine in a study there are 11 participants
with the following scores:

2, 5, 7, 7, 7, 8, 8, 9, 9, 10, 10,

The mean for the 11 scores above is 7.45

Mode Definition:

 
The mode is the most frequent score in a distribution of
scores.

Mode Example:

 For example, imagine in a study there are 11 participants
with the following scores:

2, 5, 7, 7, 7, 8, 8, 9, 9, 10, 10,

The mode for the 11 scores above is 7.
