  1. 1. DATA PROBABILITY AND STATISTICS-GRADE 4 OBJECTIVE: USE MEAN, MEDIAN, AND MODE TO DESCRIBE A SET OF DATA. Created by: SHERRI COLLIE EDN 300-002 JULY 14, 2009
  2. 2. CREDITS: PICTURES BY: GOOGLE AND POWERPOINT CONTENT AND CURRICULUM PROVIDED BY: WWW.YOUTUBE.COM WWW.YOURTEACHER.COM WWW.LEARNINGUPGRADE.COM CREATED BY: SHERRI COLLIE A MATH LESSON PLAN FOR FOURTH GRADERS
  3. 3. MAIN MENU
  4. 4. CONTENT 1.1 WHAT ARE THEY? •MEAN •MEDIAN •MODE
  5. 5. For more math tips CONTENT 1.2 press here! The Mean, Median, and Mode are summary statistics that help you describe a set of numbers in a data set.
  6. 6. CONTENT 1.3 MEAN EXAMPLE  Data Set:  It is the average 7, 6,4,6,10,8,5,2  The sum of all numbers  = the sum of all the = 48 numbers in a set  Divide the sum by the divided by the total total of the numbers in number in that data set the data set. 48/8=6  The mean is 6
  7. 7. CONTENT 1.4 MEDIAN: Data set • the value in the middle of the data set. 15, 24,49,8,50 Put them in order from lowest • half the numbers are to highest < or = to the median. 8,15,24,49,50 • half the numbers are Pick the middle value > or = to the median Median=24
  8. 8. CONTENT 1.5 Data Set: 3,4,5,5,6,7,8,10 If your data set has an even amount of numbers, Your data set would have two middle values. Take the mean of these two values to get the median. Median=(5+6)=11 11/2=5.5 Median=5.5
  9. 9. CONTENT 1.6  The Mode is the value which has the greatest frequency in the data set. Example Data Set: 3,4,5,5,6,7,8,10  The Mode of this Data Set is: 5
  10. 10. CONTENT 1.7  If there are no repeating numbers in the data set, Example: Data Set: 3,5,7,9,12,15  There is no mode.
  11. 11. CONTENT 1.8 Press for Review
  12. 12. WHAT IS THE MEAN OF THE FOLLOWING DATA SET: 3,5,7,9,12,15? a) 8 b) 7 c) 8.5 d) 5 e) 9
  13. 13. WHAT IS THE MEDIAN OF THE FOLLOWING DATA SET: 24,60,12,48,36? a) 48 b) 12 c) 30 d) 15 e) 36
  14. 14. WHAT IS THE MODE OF THE FOLLOWING DATA SET: 12, 4,8,12,15,25,18,12? a) 4 b) 12 c) 36 d) 24 e) 8
  15. 15. WHAT IS THE MEDIAN OF THE FOLLOWING DATA SET: 4, 8,10,12,15,20 a) 10 b) 12 c) 22 d) 11 e) 15
  16. 16. WHAT IS THE MODE OF THE FOLLOWING DATA SET: 8,12,15,13,16,19,20? a) There is no Mode. b) 13 c) 28 d) 14 e) 20
  17. 17. YOUR RIGHT! WAY TO GO!
