This document defines and explains how to calculate the mean, median, mode, and range of a data set. The mean is found by adding all the numbers and dividing by the total. The median is the middle number when values are listed from lowest to highest. The mode is the most frequently occurring number. To find the range, subtract the lowest number from the highest.

1. Mean, Median, Mode, and
Range
By: Zach and Sierra

2. Add up all of the numbers in
the set.
Take the sum of these
numbers and divide it by
how many numbers there
are with in the set.
The answer you get from
the division problem is the
mean.

3. Put the numbers within the set in
order from least to greatest.
Find the middle number with in the
set.
If there are two middle numbers,
find the mean of the two numbers.
The middle number with in the set
is the median

4. Find the number that occurs
the most with in the set.
This number is the mode

5. Find the lowest and highest
numbers with in the set
Subtract the two numbers
Then the answer you get is
your range

6. Now you know how to find
the mean, median, mode,
and the range within a set
of numbers.
