Document Sample
Mean_ Median_ Mode_ and Range Powered By Docstoc
					      Mean, Median, Mode, and Range
MODE – easiest to see just by looking
    - sometimes more than one
    - most popular




MEDIAN – the “middle”
    - have to be in order to be seen
    - in the middle
    - sometimes can’t be seen because it’s hiding between two




MEAN – can’t be found just by looking
    - need to calculate values to find the average




RANGE – the difference between the greatest and least estimate

      Example:           100 - greatest estimate
                          75 - least estimate
                          25 - difference

      The range between 100 and 75 would be 25.
