EXAM IS MONDAY MORNING STARTING AT 9:00 AM

review matricies, correcting homework

We started off the class today talking about the provincial math exam and what to do if you are wanting to go to the funeral on monday. What Mr.maks had concluded was to just go. You can finish that part of the exam another day it just won't be considered a provincial mark anymore. Check to see if you need a provincial mark on your transcrips to get into post secondary school. Talk to mr.maks about it if you want more information.

Then we corrected our homework. The multiple choice and question five and then reviewed.

Review of the exam

Things to know about Matrix Modelling:
-matrix operations and vocabulary +, -, x, x rules
-matrix multiplication (two-finger) helps you avoid nonsense
-transition matricies, n x n ROW matricies, "1 sum" , understand transition diagrams, STABILITY
[B] x [A] ^ n
[B] x [A]^(n+1)
-two-way networks, symmetry across a diagnol <--->
-one-way networks -----> EXACTLY, ATLEAST, AT MOST
[A], [A]^2, [A]^3, etc..

Scribe Post January 11, 2010.

Today we started going over what to expect on the exam that will take place exactly a week from this morning, on January 18th and 19th. There is a page below further explaining both days of the exam. After that we began correcting question 2 of the booklet we were given last week on sinusoidal (periodic) functions.

This Page below shows our homework for the day.

We have been assigned question 2 for homework by nine tommorow morning. Also, sin reg is stat, calc, sin reg, l1, l2, y1(vars, y thingy, y function.)

January 6 2010

Today was our first day learning about Periodic Functions, we were taught that a periodic function is a never ending repetitive sequence. A perfect example of this is an EKG.

Exam Prep

Mr. Max told us today that we can get free marks if we create a math study schedule. The schedule has to fit around our own personal schedules with work, etc. and have time written in for studying. Each of the units have to be covered by the exam on the 18th. It has to be completed by tomorrow.

*Where it says 2nd, that means it is written on the 2nd day. There are only 2 units on the 1st day, Design/Measurement and Applications of Periodic Functions.

Confidence Intervals

We have 2 weeks left of class before we have to take our Inquirey Test. The test will take place on the 18th(monday) and the 19th(tuesday). We will finish our statistics unit today and tomorrow.

We corrected the binomial questions(1-12). To figure out when to use binomcdf( and binompdf( , look for clues in the question. If a question asks for an exact answer the use pdf. If a question asks for a range of numbers that's when you use cdf. If you're wondering how to get to cdf and pdf turn on your calculator and press [2nd] then [vars]. Go to the bottom of the list and they're right beside each other. To use these apps put in the total number of trials in the first spot. Put a comma next and put in the probability. Put in another comma and put in the number you want to figure out the probability of getting.

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.
