Statistics: Science of learning from data
This includes collecting and interpreting!
This is not your
typical math course!
You will not really
calculate things by
hand, instead think
about their
meanings!
Prerequisites:
A passing grade in Algebra II
Course Expectations:
TAKE CARE OF YOURSELF: If you find that you are
having difficulty at ANY time, please talk to your
teacher.
Course Expectations:
TAKE CARE OF EACH OTHER: Allow
everyone to learn and work in this classroom.
Respect others and help when asked.
Course Expectations:
TAKE CARE OF THIS PLACE: There is to be
NO FOOD OR DRINK IN THE CLASSROOM FOR
ANY REASON.
No music devices, headphones, cell phones, hats,
sunglasses or cosmetic products are permitted in the
classroom. The item(s) will be confiscated.
REQUIRED MATERIALS: Each student is to
come prepared for class and bring the following
materials EVERY DAY:
• A 3-ring binder
• A spiral notebook, glue stick/tape, highlighters,
colored pencils, scissors (due Tuesday)
• TI-83, TI-84, or the TI-89
GRADES: Your grade will be based on the
following:
•

ATTENDANCE: AP Stats covers a considerable
amount of material. Please note the following:
• Attendance is very important. If you are absent on a
day of a new lesson, you are responsible for making up
the notes and homework before the chapter test. If you
are absent on a review day, you are expected to do the
review on your own and take the test on test day.
ATTENDANCE: AP Stats covers a considerable amount
of material. Please note the following:
• If you are absent on a test day you must make it up
within 2 days (during after school tutorial or during a
free block). This is your responsibility to schedule a
time to make up a missed test with your teacher.
ATTENDANCE: AP Stats covers a considerable amount
of material. Please note the following:
• Homework and tests will receive NO credit if the
absence is unexcused (not cleared through the
attendance office).
HOMEWORK/NOTES:
 Work is to be done on a separate sheet of paper.
See back page for homework expectations.
HOMEWORK/NOTES:
 Homework will be collected daily. It must be
complete AND every problem correct to receive full
credit. Spiral reviews are given after each test and are
due the day of the next test. Spiral reviews count as 2
homework assignments.
HOMEWORK/NOTES:
 Late work is not accepted without a pass. You
will be given 2 passes in the beginning. No work
will be accepted after the chapter test.
HOMEWORK/NOTES:
 You will be creating an interactive notebook during
the class. It will be graded on review days for the unit.
QUIZZES/FREE RESPONSES:
• Some days students will complete a quiz or a
previous released Free Response Question at the
beginning of class based on the material they have
learned.
• When students take the quiz or FR with their
assigned groups, only one will be selected from the
group to be graded. Each student in the group will
receive the score of the one that is graded.
QUIZZES/FREE RESPONSES:
• If you are ABSENT or LATE you cannot make up
the quiz. At the end of the term, the 3 lowest scores will
be dropped.
PROJECTS/ACTIVITIES:
 Throughout the course there will be some
projects and activities. Some of the projects will be
done in groups, in pairs, or individually. It is
important to come to class on activity days because
they cannot be made up.
 Late projects will be worth 50% off if they are
one class day late. Beyond that, they will not be
accepted.
TESTS:
• There will only be two tests per term. These tests are
in the format of an AP test and are cumulative. The
grades will be curved on the AP grading scale ONLY if
you complete test corrections during a tutorial.
TESTS:
It is very important to prepare for the test by
studying:
Re work homework problems
Read through your notes
Do the review tests
Review Quizzes and FRQ
Go to tutorials
Do the cumulative reviews

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?
Experiment: Do something to the
individuals, apply a treatment
(doesn’t have to be a drug)
Ex. Can sleeping for 8hrs increase your GPA?
Cause and Effect: Only experiments because a
treatment was applied in a
controlled environment.
•More than 98 percent of convicted felons are bread users.
•More than 90 percent of violent crimes are committed
within 24 hours of eating bread.
•Eighty-seven point one per cent of the adult criminals
in penitentiaries throughout the United States have
eaten tomatoes.

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
Data Analysis: Organizing, displaying,
summarizing data and asking
questions.
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 – categorical
The color of a Reese’s Pieces candy – categorical
Number of calories in a fast food meal – quantitative
The life expectancy of a nation – quantitative
Amount of college fees – quantitative
The weight of an automobile – quantitative
Who people voted for in the election – categorical
When given data, what should you ask yourself? W5HW
Who: Individuals
What: variables
Why: purpose
When: How old is the data?
Where: Where did the data come from?
How: How did they gather the data?
By Whom: 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!
Distribution: The values the variables take and
how often it takes these values
Mean: Average value. Add up numbers
and divide by # of values
Mode: Most frequent value
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
5 = 0.2 = 20%
Statistical Inference:

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.
InterActive Notebook supplies due: Tuesday
• An 8.5 x 11 spiral notebook with at least 80-100
pages
(probably will need at least 2)
• 2 glue sticks or scotch tape
• Highlighters of different colors and/or colored
pencils
• Pen and pencil with an eraser
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)

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.
What goes on the Left Side? Output goes on the left
side! Left side items include:
 Quizzes or FRQ’s
 Text information
 Analysis Writing
 Reflection Writing
 Flowcharts
 Venn Diagrams
 Pictures that help represent the material on the left
Things to Know About the Left Side
 Every left side page gets used
 Always use color…It helps the brain learn and
organize information.
Statistics
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.
What goes on the Right Side? Input goes on the right
side!
Input is all the information that you are supposed to
learn. Some examples of input are
Thrilling notes
 Lecture
 Vocabulary words
 Teacher questions
 Example questions and answers
 Sample problems
THE KEYS TO FANTASTIC RIGHT SIDES
 Always start the page with the date and section at
the top of the page.
 Right sides have odd numbered pages.
 The right page is for writing down information you
are given in class.
 Write legibly. Use highlighting and color to make
important information stand out.
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.
1. Select at least 4 items that represent what you think
will be on the AP test. Reflect on the importance of
these ideas and why you would put these ideas on
the test. Indicate how well you understand these
topics.
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!
