• 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

Mean

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

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
