WHAT DO THEY ALL MEAN?
Mean
• Is the average of a set of
numbers.
How is the mean of a set of
numbers found?
• Add all the numbers in the set
together.
• Divide the sum by the number of
numbers in the set.
• The quotient is the mean of the
set of numbers.
• Example: 20, 15, 25
– Add 20+15+25=60
– Divide 60 by 3
– The mean is 20
Median
• Is the number that is in the middle
of a set of numbers.
• (If two numbers make up the
middle of a set of numbers then the
median is the average of those two
numbers.)
