A Reflection - if you'd like, write a reflection in Google Docs and share it with Mr. C 1. Some questions are listed below to guide you. Write whatever you want that is reflective of your learning experience up to this point in AP Stat. DO NOT just answer the questions below in a Google doc

What do you like about class so far this year?

What don't you like about class so far this year?

What would you like to do more of?

What would you like to do less of?

How much effort are you putting into learning?

What would help you to learn better?

Rolling Down the River

Conduct each method of sampling and determine the average yield per plot

Skill 12.1: Know the basic concepts and terminology of sampling Skill 12.4: Report possible sources of bias in sampling methods. Recognize voluntary response and nonresponse as sources of bias in a sample survey List of types of bias and their definitions Design a biased survey

Think of a question/questions you want to investigate

What's the population you'll be sampling from?

What do you want to know about a population (parameter you're trying to investigate)

Proportion or average?

How would you conduct a survey that is biased in the following ways?

Skill 12.1 Know the basic concepts and terminology of sampling Skill 12.2. Understand the value of sampling to estimate population parameters from statistics calculated on representative samples drawn from the population Skill 12.4: Report possible sources of bias in sampling methods. Recognize voluntary response and nonresponse as sources of bias in a sample survey Sampling Variability - count the number of g's in a story

Reassessment

You may use your formula sheet

Non-reassessors
1. Conduct a simulation - Complete 10 trials for each simulation and record an average/proportion for all trials

42% of drivers pass their driver's test on their first attempt. If they fail the first attempt, they have a 72% chance of passing on each additional attempt. Design and conduct a simulation for the number of attempts that can be expected to pass a driver's test.

Design and conduct a simulation to determine the number of hearts that can be expected in a 5 card poker hand

30% of nests in a chicken coop have 4 eggs, 45% have 3 eggs, and the rest have 2 eggs. Design and conduct a simulation to determine the number of nests you can expect to check to get one dozen eggs

Conduct a simulation of your own design

2. Finish your toaster regression project and share it with me on Google Docs
3. Organize Unit I and Unit II skills pages on the wiki

Homework
Think of a situation that can be simulated using a random number table

Monday December 13, 2010

Unit II Test Discussions Homework Think about this...if you flipped a fair coin 100 times, how many heads would you get?

If this process of 100 flips were repeated, what would we expect?

Friday December 10, 2010

Collect your sample according to the method you developed yesterday

Post your sample (as just teacher's last names) in the discussion forum of the home page

Teachers that were sampled, largest names appeared the most frequently in our samples

Skill 11.1. Conduct a simulation to simulate random outcomes for a real-world situation Objectives 1. Be able to recognize random outcomes in a real-world situation 2. Be able to recognize when a simulation might usefully model random behavior in the real world Lesson 1. Do Teachers Have Tattoos?

What % of teachers at North Penn High School have tattoos?

How would you determine this percentage? (Groups of 3)

Census

Samples - come up with a way to determine just how you would sample from both HS and the entire district

Figure out a way to get a representative sample of teachers

Then conduct your sample

Suggestions/illustrate strategy on the board

Look at the results of your sample, is your sampling method "fair"?

Random Number Table and Random Sampling Techniques

Question now becomes what percentage of students at North Penn have tattoos?

How about teachers in the North Penn School District?

2. Begin to think about what you want to investigate about the North Penn Community

Everyone else:

Toaster Regression Project (due by Monday 12/6/2010, shared with Mr. C on Google Docs) Skill 9.1. Understand appropriate cautions to take when fitting a regression Inflation Data

Scatterplot of inflation rates over the years

Would be better to look at and report subgroups
