  1. Mean, Median, Mode & Range

  2. Outlier • An outlier is a data item that is much higher or much lower than items in a data set. • 1, 2, 5, 27, 3, 4

  3. Definition • Mean– the average of a group of numbers. 2, 5, 2, 1, 5 Mean = 3 BACK

  4. How to Find the Mean of a Group of Numbers • Step 1 – Add all the numbers. 8, 10, 12, 18, 22, 26 8+10+12+18+22+26 = 96 BACK

  5. How to Find the Mean of a Group of Numbers • Step 2 – Divide the sum by the number of addends. 8, 10, 12, 18, 22, 26 8+10+12+18+22+26 = 96 How many addends are there? BACK

  6. How to Find the Mean of a Group of Numbers • Step 2 – Divide the sum by the number of addends. 1 6 6) 96 # of addends sum 6 3 6 3 6 BACK

  7. Definition • Median– the middle number in a set of ordered numbers. 1, 3, 7, 10, 13 Median = 7 BACK

  8. How to Find the Median in a Group of Numbers • Step 1 – Arrange the numbers in order from least to greatest. 21, 18, 24, 19, 27 18, 19, 21, 24, 27 BACK

  9. How to Find the Median in a Group of Numbers • Step 2 – Find the middle number. 21, 18, 24, 19, 27 18, 19, 21, 24, 27 BACK

  10. How to Find the Median in a Group of Numbers • Step 2 – Find the middle number. 18, 19, 21, 24, 27 This is your median number. BACK

  11. How to Find the Median in a Group of Numbers • Step 3 – If there are two middle numbers, find the mean of these two numbers. 18, 19, 21, 25, 27, 28 BACK

  12. How to Find the Median in a Group of Numbers • Step 3 – If there are two middle numbers, find the mean of these two numbers. 46 21+ 25 = median 23 2) 46 BACK

  13. Definition • Mode– the number that appears most often in a set of numbers. 1, 1, 3, 7, 10, 13 Mode = 1 BACK

  14. How to Find the Mode in a Group of Numbers • Step 1 – Arrange the numbers in order from least to greatest. 21, 18, 24, 19, 18 18, 18, 19, 21, 24 BACK

  15. How to Find the Mode in a Group of Numbers • Step 2 – Find the number that is repeated the most. 21, 18, 24, 19, 18 18, 18, 19, 21, 24 BACK

  16. Definition • Range– the difference between the greatest and the least value in a set of numbers. 1, 1, 3, 7, 10, 13 Range = 12 BACK

  17. How to Find the Range in a Group of Numbers • Step 1 – Arrange the numbers in order from least to greatest. 21, 18, 24, 19, 27 18, 19, 21, 24, 27 BACK

  18. How to Find the Range in a Group of Numbers • Step 2 – Find the lowest and highest numbers. 21, 18, 24, 19, 27 18, 19, 21, 24, 27 BACK

  19. How to Find the Range in a Group of Numbers • Step 3 – Find the difference between these 2 numbers. 18, 19, 21, 24, 27 27 – 18 = 9 The range is 9 BACK

  20. What is the range? 29, 8, 4, 8, 19 4, 8, 8, 19, 29 29 – 4= 25 BACK
