  • 1. BEGIN……… Mrs. LeCrone Rm 205 All clip art courtesy of Microsoft Clip Art Gallery
  • 2. Back to beginning Continue To Example
  • 3. • You can find the mean of a set of data by finding the sum of the numbers you have and dividing by the amount of numbers you have. 7 numbers Set of numbers: 5, 7, 7, 10, 12, 14, 15 5+7+7+10+12+14+15= 70 70/7=10 Mean=10 Back to beginning Continue to Activity
  • 4. Mary wants to know how high she can jump. She realizes that she can’t rely on just one jump so she decides to record how high she jumps each of 15 times. The following is a graph she made to record her data: 67 66 65 64 63 62 61 60 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 What is the first step in calculating Mary’s MEAN Jumping height? Find the height she Add up all of the Put her jump heights in an jumped most often heights she jumped ordered list
  • 5. 67 66 65 64 63 62 61 60 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 What is the sum of Mary’s jumping heights? 961 inches 820 inches 1052 inches
  • 6. Now that we know the sum is……… 961 inches What do you do next? Multiply by the Subtract the sum from Divide the sum by the number of jumps the highest Jump number of jumps
  • 7. Now we need to divide the sum of all of Mary’s jumps by the number of jumps she attempted. What will this problem look like? 961 ÷ 15 = 15 ÷ 961 = 961 – 15 =
  • 8. Start Over End Activity Now that we know that 961 ÷ 15 = 64.06 we can make some conclusions about Mary’s jumping height. Use activity to write three OBSERVATIONS you can make about Mary’s Jumping height.
