Storyboard Text

  • Let’s see, when you add 7+7+8+6+5+4+9+10+2, then divide it by 9, what do you get?
  • First, I’ve got to put the data in order. 2,4,5,6,7,7,8,9,10. Now I’ll just go to the center and figure out what is the number in the middle, the median!
  • 2,4,5,6,7,7,8,9,10. Now let’s see, are there any numbers that appear multiple times? Yes! I’ve found the mode!
  • So, did everybody find what they needed to find?
  • Yes We Did!
  • So when you add up all of the data, then divide it by 9, you get 6.44 as a repeating decimal. So the mean is 6.44
  • What I did was put all of the data in sequential order, and counted from the outside in to see what number was in the center. The median is 7.
