Stocks
Yesterday we did mental math and then our class got interrupted by our principal and vice principal... to practise what to do if we ever have a lockdown! :D

At the beginning of the class we corrected our homework for yesterday. Then we went on the tsx website and created login names. Then Mr. Max magically gave us $10,000 to buy into 5 differant stocks. We will be watching them till the end of the course and we will see who made the most money. The big guy then created a spread sheet to organize our stocks and how many shares we bought. For those who dont no how to make them very good he's saving his on the transfer drive so you can play around with it.
This is the instructions for the project

This is what the spreadsheet Mr. Max created.
MONDAY, IMPORTANT DO NOT MISS!!!

November 15
Well we started off the day by chekcing the homework that we had due , VI-D-4 # 2,5,6,7 and assignmen 2 Read VI-D-5 to VI-D-7 Questions 1, and 2. Then Mr. Max went over the homework. We went over Lesson 2 Investment Choices.
Assignment for tomorrow Lesson 2 VI-D-9 and VI-D-11 Questions 3 and 4.

We started off the class with some Mental Math( make sure you handed in your papers!!) to get our brains warmed up and than sighned up for the Provincial Standards Test and than jumped into... Project Portfolio.. and starting our next unit on Investments..
Consumer Math Project Schedual

2. Thursday November 22nd
3. Monday November 26th
Due @ 10:00 am .... time is ticking!!
Things we've accomplished; Personal Finance , Government Finance, Stats
Things yet to do; Invesments, Design/Measurment, Variation Formulas
This means that.....
WE ARE HALF DONE THE COARSE
Investments
What is something YOU think would be good to invest NOW for in the future?
Make sure you do your homework!!! ha ha

Statistics Summary Notes
Lesson One-Percentiles
Percentile Rank-tell's us the percentage of all scores that fall below a particular score.
P.R=B+0.5E*100/n
B= Below a given score
E= Equal to the given score, including the given score
N= total number of raw scores
Lesson 2: Measures of Variability- Standard Deviation
Range- in a set of numbers os the difference between the largest and the smallest numbers in a set.
Step 1: Determine the mean.
Step 2: Determine the difference between each score, and the mean.
Step 3: Determine the square of each of these differences.
Step 4: Determine the sum of the squares.
Step 5: Divide the sum of the squares by n-1
Step 6: The standard diviation, calculate square root of this number.
Lesson 3- Normal Distibution
Characteristics of the Normal Curve:
1: Bellshaped- infinite in both directions
2: Symmetric about the mean.
3: Median ( middle number)
4: approxiatemly all of the data.
Lesson 4: Correlation Coefficient
Interpret a number that measures a relationship between two sets of values is the correlation coefficient or r.
Three ways that data can be described on a scatterplot:
1: Positive Correlation- means that as one variable increases, another variable also increases, or thats as one variable decreases, another variable decreases as well. Positive Correlation falls between the values 0 and +1.
2:Negative Correlation- means that as one variable increases, another variable decreases, or that as one variable decreases, another variable increases. It falls between 0 and -1.
3: Zero Correlation- means that the variable in question essentially have nothing to do with each other and, therefore, cannot be said to be related. It's very close to or equal to 0.

Statistics - Percentile Rankings
P.R. are used to compare individual scores to groupe scores. It is called this because a single value is calculated in relation to all there values..
P.R. = (B + 0.5E) . 100
--------------
n
B = the number of scores below the given score
E = the number of scores equal to a given score ( if there are no other scores equal to use 0)
n= the total number of scores
Measures of Variability - Standard Deviation
Range = the diffrence between the largest and the smallest
Standard Deviation = a measure of variability
To calculate the standard deviation of a groupe of numbers it can be determined by using these steps
1. Calculate the mean of the numbers.
2. Determine the diffrence between each number
3. Determine the squares of the differences
4. Determine the sum of these squares
5. Divide the sum of the squares by n -1
6. Calculate the square root of this number
Normal Distributions
Characteristics of the normal curve :
1. Bell Shaped - infanite in both directions
2.Symetric about the mean
3. median
4. is appromiatly all of the data
Correlation Coefficient
Correlation Coefficiant = how to interpret a number that measures a relationship between two sets of values.
Positive Correlation = means that as one variable increases another variable also increases
-1 <> 1
- -
( the range of values for all correlation coefficiants is always between the above)

Test on monday.
I found a standard Deviation calculator at http://invsee.asu.edu/srinivas/stdev.html it works really good for checking you answers.
