  1. 1. Measures of CentralTendencyBy L.D.
  2. 2. Table of Contents Slide 3: Foreword Slide 4: How to Find Median Slide 5: How to Find Mean Slide 6: Mini Lesson: Mean Names Slide 7: How to Find Mode Slide 8: How to Find Range
  3. 3. Forward We will be using the problem below as an exampleproblem to find the median, mean, mode and range. Marcella was played 5 ballgames where she scored thescores below. 28, 18, 24, 22, 18 The best thing to do for the next few problems is put thenumbers in numerical order. 18, 18, 22, 24, 28
  4. 4. How to Find Median You organize the numbers in numerical order. 18, 18, 22, 24, 28 The number of middling value is the median, in this caseit is 22. Sometimes there is no median at all.
  5. 5. How to Find Mean Numbers: 18, 18, 22, 24, 28 To find the mean you add up all the numbers. 18 + 18 + 22 + 24 + 28 = 110 Then you take the 110 and divide it by the number ofnumbers, which is 5 in this case. 110/5 = 22 Mean: 22
  6. 6. Mini Lesson: Mean Names Another word for “mean” is “average”.
  7. 7. How to Find Mode Numbers: 18, 18, 22, 24, 28 To find this one you take the number that has the most ofitself in the list and call it your mode. In this case it is 18 There can be multiple duplicates of a number, but the modewill only be one number. It is easier to find the mode if the numbers are in numericalorder. Mode: 18
  8. 8. How to Find Range Numbers: 18, 18, 22, 24, 28 To find the range you take the maximum or the largestnumber and minus the minimum or smallest numberfrom it. 28 – 18 = 10 Range : 10
