Study Schedule

Our blog projects are due TODAY!

We will get assignment marks for:

We are Encouraged to study for the Exam...By making a study schedule, and handing it in on Monday (this can also be a list).
There are 2 parts

1. An actual schedule that has dates and times (max 2h)

2. Block the content, what this means is are you going to organize your schedule by content, skill, study technique...IE: don't study stuff you know.
"Jump both feet right into the material you don't understand"

EX:"By this date i plan to have finished studying and understanding this unit

Exelerated Math is due by the 22nd.
.
We can also get old exams to practice on, just go ask Mr.Max for one!

Monday May 4th

We were suppose to have questions 5 and 6 from our Personal Finance booklet. We are pretty much done personal finance with these two questions.

We may be getting our last test back (Hurrah!)

We got a progress mark today, hope everyone did something on Friday!

Monday April 20th

There is a test Thursday on Statistics.

The 3 things we did today are:

1. Homework check from the questions on Friday


2. C.C.C! Video on Demand.

If you go to the school website, on the front page if you go to students there is a link to get to the site. you use your user name and password from logging in at school (the one you use to get on any computer in the school).

You put in a key word and can search what you want to look for.

The point is you can look up anything you need to learn about and there is probably a video on there.

Also all of these videos are download-able, so you can put it on your ipod or phone using itunes. Not gonna lie it is kinda cool and really helpful.


3. We also got a new hand out on Binomial Distributions.

We are to do Questions 1-12 for tomorrow. They are on the last page of the hand-out we got today.

Variability and Statistical Analysis

Hello Everybody! Welcome back from Spring Break!

Today in math we started by doing Mental Math.

We started the next Unit which is: Variability and Statistical Analysis.

We are leaning Standard Deviation.

We were then asked how many kms we live from the school, rounded to the nearest km.With this data we made a table in Excel, and we found out the mean distance is 16.5km. We then found the difference from the mean, and you were either positive or negative depending on if you lived inside or outside the mean area (positive if you are outside, negative if you were inside). We then found the mean differences squared, we found that all the numbers were positive.
We then found the sum of the differences squared, then we divided this number by how many people there were that gave data, then we found out the standard deviation.

Standard Deviation is measuring "spread", closeness from the middle or average, and if every number is the same there is no deviation.

To calculate Standard Deviation on your calculator you:

PUT THE DATA INTO A LIST, PRESS STAT, THEN CALC, THEN PRESS ENTER TO TAKE 1 VAR-STAT TO YOUR HOME SCREEN, THEN AT THE HOME SCREEN PRESS SECOND, THEN THE NUMBER DEPENDING ON YOUR WHAT NUMBER YOUR LIST IS, FOR EXAMPLE YOU DATA IS IN LIST ONE THEN PRESS SECOND, 1. L1 WILL APPEAR, PRESS ENTER.

There are 11 symbols we are supposed to look up for tomorrow. These are the symbols that appear when you enter a Standard Deviation equation into your calculator.

Exercise 5 Question #5

The Question:

Winners at a science fair are determined by a scoring system based on five items with different weights attached to each item. The items and associated weights are the summary of background research- weight 3; experimental procedure- weight 5; research paper- weight 6; project display- weight 8; and, creativity of idea- weight 4. Each project is judge by grading each of the five items on a scale from 0-10, with 10 being the highest. The total score for a project is derived by adding the products of the corresponding weights and points for each item.

a) Create a 1x5 matrix giving the weights of each item. Label it A.

b) Create a 5x7 matrix to show the number of points gained by each contestant. Label it B.

c) What does the matrix product AB indicate?

d) Calculate AB and record it. Summarize the results of the science fair.

How you get there:

a) [3 5 6 8 4]

We arrived at this answer by looking back at the question, and using the weight numbers provided there.

b)

This table is given to you in the question so all you have to do is copy it.

c) The matrix product of AB indicates that it is a 1x7 representing the overall score each person received.

You can arrive at 1x7 by taking the dimensions of the matrix A and matrix B,

[A]=1x5 5x7=[B]

the outer dimensions show what size the answer will be, and the inner show you can multiply it.

d) [A] [B]= [223 231 227 229 220 216 228]

This is done simply by entering in the two matricies into your graphing calculator and multiplying them together in this order. If you multiply [B] [A] it does not work, you will get a totally wrong answer.

The results of the science fair are as follows:

First Place- Jane 231

Second- Kathy 229

Third- Terri 228

Fourth- Bryan 227

Fifth- Peter 223

Sixth- Mary 220

Last Place- Chris 216
