Let's Begin!
Preliminary Chapter – What is Statistics?
4 main themes:
(compare graphs and numbers)
I. Exploring data
II. Sampling & Experimentation
(collect data)
(Probability and Simulation)
III. Anticipating Patterns
(Make conclusions)
IV. Statistical Inference
Last Year’s Profits
Last Year’s Profits
Population:
Entire group of interest
Sample:
Representation of subjects from the population
Where do you get good data?
Available Data:
Data that was produced in the past, can be good or bad!
Census:
When you survey everyone in the population of interest
Survey:
Questionnaire designed to gauge public opinion and predict what the population believes
Observational Study:
Don’t interfere with the individuals, no treatment applied. Includes surveys.
Ex. What percent of students have cell phones?
Do something to the individuals, apply a treatment (doesn’t have to be a drug)
Experiment:
Ex. Can sleeping for 8hrs increase your GPA?
Only experiments because a treatment was applied in a controlled environment.
Cause and Effect:
Example #1:
I want to know if Steele Canyon students like school. How can I find out?
Example #2:
Do people wash their hands every time after going to the bathroom? Design an observation.
Survey if they wash hands
Watch to see if they wash their hands
Example #3: In adults, moderate use of alcohol is associated with better health. Some studies suggest that drinking wine rather than beer or spirits yields added health benefits.
a. How would you determine if wine caused better
health than beer?
Experiment. Assign people into a drinking wine, beer, hard liquor, or no alcohol group.
b. What else could influence your results? What are some examples that could influence health that should be considered?
If they exercise, prior health concerns, how much they drink
Organizing, displaying, summarizing data and asking questions.
Data Analysis:
Individuals:
Objects described by a set of data. Can be people, animals, things
Variables:
Characteristic of an individual.
Categorical Variables:
Places an individual into one of several groups or categories
(favorite color, ethnicity)
Quantitative Variables:
Takes numerical values for which arithmetic operations (like adding) make sense.
(age, height, weight)
Example #4:For each of the following variables, state whether it is categorical or quantitative:
Whether a penny lands on heads or tails –
The color of a Reese’s Pieces candy –
Number of calories in a fast food meal –
The life expectancy of a nation –
Amount of college fees –
The weight of an automobile –
Who people voted for in the election –
categorical

When given data, what should you ask yourself?
W5HW
Who:
What:
Why:
When:
Where:
How:
By Whom:
Individuals

purpose
How old is the data?
Where did the data come from?
How did they gather the data?
Who gathered the data?
Example #5 Here is a small part of a data set that describes the fuel economy (in miles per gallon) of 2004 model motor vehicles:
a. Answer the key questions (who, what, why, when, where, how, and by whom).
Who: 2004 vehicles
What: Make and Model, vehicle type, transmission type, # of cylinders, City MPG, Highway MPG
a. Answer the key questions (who, what, why, when, where, how, and by whom).
Why: Compare MPG in different cars
When: ?
Where: ?
How: ?
By whom: ?
b. Which variables are categorical? Quantitative?
Categorical:
Make and Model,
Vehicle type,
transmission type
Quantitative:
# of cylinders,
City MPG,
Highway MPG
c. Can you assume that manual transmissions always have better mpg? Explain.
No,
Not enough data collected. Only one manual transmission in the list!
The values the variables take and how often it takes these values
Distribution:
Average value. Add up numbers and divide by # of values
Mean:
Most frequent value
Mode:
Probability:
Chance behavior that is predictable in the long run
Example #6
You are taking the AP Stats exam. A multiple choice question is provided with answers a-e. You have no idea what the answer is! What is the probability you guess the correct answer?
1

Statistical Inference:
Making guesses on the population given many samples from that population.
What will happen in 5 years?
Example #7
When you opened your bag of chips you were disappointed to see how empty the bag already was. The bag said it weighed 1.5 oz. You went and measured and discovered your bag weighed 1.45 oz. Can you say that the company should fix their machine?
No!
Sample size is too small!
Keeping InterActive Notebooks in Statistics
InterActive Notebooks will be used in this class to help you learn and remember key scientific concepts. Why does this type of notebook work? This notebook styles uses both the right and left brain hemispheres to help you build neural networks. By providing space for you to record information and refer to it quickly, this too increases your ability to remember and use the information later. You’ll also have an opportunity to interact creatively with the new knowledge you’re gaining.
Instructions
See the sample below for the set-up for the first six pages and the back. Number all pages that follow in the upper right hand corner. Left side pages are even; right side pages are odd.
Left pages = output (even numbered pages)
The left spiral page shows your understanding of information. Basically it’s your manipulation of the information from the right side. You work with input from the right side, but present it in your own way. This includes interacting with the book.
Right pages = input (odd numbered pages)
The right page is for writing down information you are given – when your teacher lectures.
In the back= Formula sheets (labeling each formula) and Tables, Calculator tips
(inside cover)
Students glue/tape in a copy of the InterActive Instructions
(left side) 2
Students glue/tape in copy of left-side guidelines.

Notebook Title Page:
Course, Teacher, Student’s Name, Block
(left side) 4
Students glue/tape in a copy of the Reflection page Rubric for first unit
(right side) 5
Students construct a title page for the first unit of study. Title, Graphic, Date
(right side) 3
Students glue/tape in copy of right-side guidelines.
(BACK)
Glue/Tape formula sheet and Tables (7pgs) and begin a list of calculator tips (3-4pgs)
(left side) 6
Students write in a table of contents for the first unit.
Keeping InterActive Notebooks in Statistics:
THE LEFT SIDE
The left page demonstrates your understanding of the information from the right side of the page. You work with the input and interact with the information in creative, unique and individual ways. The left side incorporates and reflects how you learn statistics as well as what you learn in statistics.
organize information.

Keeping InterActive Notebooks in Statistics:
THE RIGHT SIDE
Interactive notebooks will be used in this class daily to help you learn and remember important chemistry concepts. Why do they work? This notebook style uses both the right and left hemispheres of the brain to help you sort, categorize, remember and creatively interact with the new knowledge you are gaining. The more you process information the more you begin to understand it. This leads to longer retention.

Keeping InterActive Notebooks in Statistics:
THE REFLECTION
Toward the end of each chapter, you will be called upon to reflect upon your work. This writing sample begins on the left side on the notebook and continues on the right. While there is no required length, high quality reflection uses 1-2 pages of the notebook.
2. Indicate your overall rating of your notebook based on the rubric. Explain why you have earned this rating. Has your notebook improved from past notebooks?
3. What specific study skills have you employed to be successful in this class? What organizational strategies appear in the notebook helped you learn the most? Elaborate.
4. What are your goals for improvement in the next chapter? List specific areas in which you feel you need to improve or need help improving.
5. What specific changes would you like to see in this class? Explain.
High Quality Reflection: A high quality reflection includes your consideration of the following in reference to your best work: what you learned from the activity, how you learned from it, what aspects of the work were high quality, what you would do differently in the future (and why), what makes you proud of this particular work, what made the activity worthwhile for you, how does this work impact your view of the world, what information did you learn that was new to you, etc. High quality reflection also examines your skills as a student and as a statistician. Skills you might discuss are organization, analysis, logic, creativity, thoroughness, accuracy of information, ability to put new information together, understanding new concepts, etc. Please note: Reasoning that it was “fun” or just that you like it, is NOT an adequate reflection!
