Math In Hopscotch | Part 2 | Finding and Revealing the MMM
This storyboard does not have a description.
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.
