It's Today!

For those of you who've forgotten, I'll be in my classroom today, Wednesday, December 30, from 1:00 until 3:00.

See you then.

Binomial Distribution

Christmas Trivia started off this very cold Tuesday morning in room 204.. Hopefully we win..

Today Mr. Max gave us a booklet that has questions all about Binomial Distribution. He showed us an example on ronblond.com about true and false test.

Tomorrow 12 questions on the booklet are due and 2,9, and 13.

December 11th/09 - Z-Scores

So today we had metal math and after he came around and gave a homework check for the 1st question in the Statistics Review Booklet. After giving the homework check, he corrected the question with us. You can solve Normal Distributions either by calculator or a site called www.ronblond.com. When you use your calculator you go 2nd VARS and normalcdf(. You enter four numbers into your calculator, first you put the lowest value, then the highest, then the mean, and finally the standard deviation. Note: If you like using spreadsheets to solve problems there is a STATISTICS spreadsheet located in "stuff you can use on the exam". We then started a new lesson called Z-scores. The equation for Z-Scores is Z=x-mean) divided by the standard deviation. It is pretty straight forward and goes along side with the Normal Distribution lesson. The assignment for today is to finish 9,13 and do 2.

Normal Distribution

Today in class, we went over the Normal Distribution Curve. The Normal Distribution Curve is essentially the theory and practice of applying a histogram ( graphical display of frequencies), to the following characteristics:
- symmetry about the mean
-follows the rule " 68-95-99.7
-mean=median=mode

* also bring something for the Christmas cheer board

Accelerated Math

Today was a long block and we started off with mental math. We then had to go talk to mr.max about our marks and how we can get them higher. In the mean time everyone worked on their accelerated math, as 14 objectives are due.

mean, median, and mode.

Today we are doing mean, median, and mode on a spreadsheet. At the 8 minute mark, Mr.Maks explains how to make the mean distance from the school. This video shows you how to get all the information from your list using your calculator, ( 1-var stats).
ON the calculator
x= mean
EX= Sum of entire list
EX2= Sum squared
Sx= Standard deviation of the sample
ax= Standard deviation of the population
Population standard deviation measures how varied the data is, relative to itself. (How spread out the numbers are)
i.e. - data set with no "spread"

-> std. dev. close to 0
i.e. data set with much variation
->std. dev. is high

Variability and Statistical Analysis

Today we learned about Variability and Statistical Analysis. He showed us how to do it on excel and built in programs such as average and sum that we could use to speed the process up. Than he showed us how to do it on our calculator. We enter the information into our list that are under stats than you go back into the stats menu and slide over to calc. From there its 1-VAR Stats, L1 and enter. All the information you need is there for your answer.

Mutually Exclusive and Inclusive Events

Today we started off class by watching the Rate&Review that we do every year to vote on which advertisment we think is most effective on us to not smoke. Mr.Max told us today that our Probability Everything test is on thursday. We then did notes and examples on Mutually Exclusive Events and Mutually Inclusive Events. Here are the notes on these:

The end of class Mr.MAx gave us to work on accelerated math and questions in our work booklets. This is what we did today!
