TEACH A LESSON presents
• Edgar Eatmon
• Dy Monquae Pates
• D. M. Smith Middle School

2
Vocabulary
• Mean-the average of a set of data.
• Median-the number in the middle of the set of
data in order from least to greatest
• Mode-the number that appears the most in the
set of data.
• Range-the difference of the smallest and the
largest number in the set of data.

Mean
• Step1
number of data you have.
• Ex 99,98,79,89,100,95,97,80,95,95
• Place in order from least to greatest. Then,
• Divide by the number of data you have.
• 999879891009597809595927
• 927\1097.2

4
Median
• Step2
• List your numbers in order from least to
greatest. Then, pick the number that is in the
middle. If you have two numbers, add them up and
divide them by 2.
• Ex79,80,85,85,89,90,91,92,95,99
• 8990179 179\289.5

5
Mode
• Step3
• Look at your numbers and see which one appears
the most. You might have more than one number
that appears the most.
• Ex 97,78,88,84,88,97,97,76
• Mode is 97

6
Range
• Step4
• List your numbers in order from least to
greatest. Then subtract the smallest number from
the number.
• Ex78,88,88,91,95,97,99,100
• 100 -7822

PROBLEM 4
• What is the mean, mode, and range of the set of
data.
