  1. Averages Handling Data

  2. Aims To find the Mean, Median, Mode and Range of a given set of data.

  3. Hey diddle diddle, the median’s in the MIDDLEyou ADD and DIVIDE for the meanthe mode is the MOSTand the range is the DIFFERENCE between

  4. Mean • To find the mean you add all the numbers together and divide by how many numbers there are Find the mean of the following: 3, 6, 1, 4, 5, 5

  5. Mean • To find the mean you add all the numbers together and divide by how many numbers there are Find the mean of the following: 3, 6, 1, 4, 5, 5 3+6+1+4+5+5 = 24 24 / 6 = 4

  6. Mode • The mode is the number that occurs the most Find the mode of the following: 2, 3, 4, 5, 3, 4, 5, 3, 2, 6, 2, 3, 7, 3, 9, 3

  7. Mode • The mode is the number that occurs the most Find the mode of the following: 2, 3, 4, 5, 3, 4, 5, 3, 2, 6, 2, 3, 7, 3, 9, 3 Mode = 3

  8. Median • The median is the middle number of an ordered set of data Find the median of the following: 4, 3, 6, 7, 4, 5, 2, 3, 2

  9. Median • The median is the middle number of an ordered set of data Find the median of the following: 4, 3, 6, 7, 4, 5, 2, 3, 2 Order them: 2, 2, 3, 3, 4, 4, 5, 6, 7 Median = 4

  10. Range • The range is the difference between the largest number and the smallest number Find the range of the following data: 12, 45, 66, 23, 34, 55, 11

  11. Range • The range is the difference between the largest number and the smallest number Find the range of the following data: 12, 45, 66, 23, 34, 55, 11 Range = 66 – 11 Range = 5

  12. Page 271 Q1 – Q7

  13. Plenary Find the mean, median mode and range of the following set of data 9, 10, 13, 8, 10 .

  14. Plenary Find the mean, median mode and range of the following set of data 9, 10, 13, 8, 10 Answers: Mean = 10 Median = 10 Mode = 10 Range = 5
