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.

Tomorrow, we will spend some more time exploring the idea of what happens when a mark is missing, but we know what the mean is.  This note will relate to a few photos I will post.

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)

The idea of an average or mean is a way to level out the information.
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
