Algebra I (3/31/10) Experimental Probablility

Experimental Probability (also called Relative Frequency) is discussed.

The Theoretical Probability of a coin toss is as follows:

P(H) = P(T) = 1/2 = 0.5 = 50%

Using different denominations of coins, small groups will conduct 100 trials of coin tosses, tabulate the results, and write up the results and conclusions.

Results from each class will be posted at the end of the day.

A host of Probability information and videos can be found below:

http://www.onlinemathlearning.com/math-probability.html



Groups:

%H %T
50 50 Because we flipped coin so wildly
46 54 We didn't throw it the same each time
50 50 True random flipping
60 40
44 56
49 51 good flipping
60 40 one side must be heavier than the other
50 50 the more flips you do the closer to the theoretical we get
44 56 could have flipped coin more randomly

Average: P(H) = 453/9 = 50.333 P(T) = 445/9 = 49.667

How to create a teacher website in 5 minutes

... okay, in five minutes each step!

I don't have a lot of time to work on this today, so hang on, here's the quick-n-dirty version.

1. Sign up for a free GMail email address (mail.google.com or www.gmail.com) You will need this in order to log into the free website hosting resource, Blogger.com

2. Go to www.blogger.com and log in with your (new) GMail address and password. Spend some time setting up the look and feel of your blogger site. You're now 3/4ths of the way through.

3. Go to Scribd.com (www.scribd.com) and create and account there. This is where you will host the PDF files you will create with the Promethean Board (how to do this is covered in the video segment.)

4. I use Microsoft Movie Maker to make the video segments. They are uploaded directly to Blogger.com (I do not use Youtube.com due to it being blocked at school, etc.) The limit is 100 megs per clip, so choose a middle of the road video resolution. I use 340 kbps and it weighs in at 2 megs per minute. This will give me more time than I should ever need for a single clip.

In the interest of time, the instructions are in the video. I will help you all that I can, but please remember that I stay after school M-Th and my planning time is precious.


I hope this helps,
