Working towards figuring out what to do when there is a missing mark in a set of data
This particular skill involves some Algebra and understanding of how mean works. Here is a short video which introduces the first portion of the concept. Sorry, there is no sound.
In this graph, it is meant to show my results on a series of 5 tests marked out of 10. In the first shot, all of the marks are the same; they are all 8/10. For the five tests, the total number of marks equals 40 and the mean equals 8 (40 marks divided by 5 tests). In the last part of the movie, I moved around the marks, but I did not add or take away any of them, so the mean remains 8.
Here is a similar example, with the same number of cubes:
 |
| 5 tests, all with the score of 8/10. |
 |
| I think the results are different from the movie, but the idea is that the 40 marks are still there, but distributed differently. |
The following images are taken from an old episode of Math Talk, which used to be on PBS.
 |
| This image represents the characters and how many donuts they ate in a year. You can see that not everyone ate donuts. |
 |
| If you calculated the mean, you will see that it suggests that everyone ate 200 donuts (0+300+100+ 400 = 800 divided by 4 = 200) |
This photo relates to the idea of the Ideal Average Sum which is explained in this note that will be jotted down tomorrow:
 |
| At this point, I will not comment about the missing number in a set of data. I will save that for another time. |
Media project: Sample #2
David brought in an ad featuring a photo from one of his visits to Camp Ooch. I thought this might be neat to provide another example of the requirements for the upcoming Media assignment.
Time will be provided, tomorrow, to further develop the assignment
Homework
- Math test on Friday on Mean, Median, and Mode
- Media project due on April 10
