STATISTICS 200 SECTIONS 1-3: (CLASS 1) SPRING SEMESTER 2016
ELEMENTARY STATISTICS
Welcome Stat 200 Students: I teach because I believe that everyone has the capacity to learn. It
has been a privilege to be able to teach Stat 200 for the past 27.5 years at Penn State. This is one of
my most challenging and daunting undertakings in life. Yet my passion remains as fervent as it was
on the first day that I walked into a classroom. I have devoted so much time and energy to this
course because it gives me the best opportunity to impact students who are mostly from nontechnical
majors and will only take one statistics course. Statistics permeates everyday life.
Learning is about the construction of knowledge. The key for success is to find the optimal way to
construct knowledge so that deep and life-long learning can take place. I look forward to facilitating your learning of
statistics. Best wishes. Pat Buchanan, Senior Instructor of Statistics

COURSE OVERVIEW & GOALS:
Overview: In today’s world, we find “big data” driving decisions made in every aspect of life. Statistics is a
discipline dedicated to unraveling the mystery of making such decisions when faced with uncertainty. More
precisely, statistics is the art and science of using sample data to make generalizations about populations.
The objective of this course is to explore and apply basic statistical concepts and procedures that are used
when analyzing data.
What you should discover is that statistics is not just another math course. While you will be exposed to
new terminology and concepts, much of the time you will use statistical software to solve problems that
require quantitative solutions. Math is said to be the language for communication with both science and
much of the social sciences. Statistics provides the structure for this communication.
You will not be inundated with repetitive calculations but instead will explore data with a context. Basic
algebra is the only prerequisite. The second part of the course is more technical. Success in this course
requires an ability to apply reasoning skills over memorization. Additionally, you will need to integrate new
material with previously-learned material throughout the semester. You are strongly encouraged to read
reputable news sources where you can see how statistics can be applied to every-day life.
Two Goals:
1. To understand the scientific method from a statistical perspective
be able to identify questions, collect evidence, discover and apply tools needed to interpret the
data, and communicate results. While you may never conduct a scientific study, it is still
possible that you may encounter data or statistical results over the course of a career.
2.
To become good “statistical” citizens
be able to: examine the information that you are inundated with, think critically about it, and
then use it to make good decisions. Science plays a key role in solutions for many of today’s
problems.
Note: A copy of the twenty-three learning objectives are posted on Angel
OTHER PEOPLE WHO ARE A PART OF OUR LEARNING COMMUNITY
Teaching Assistants (TA’s):

oversee the computer lab meetings – primarily serve as facilitators – don’t just give answers

work with a team of other graduate students who will hold shared office hours (SOH)

respond to emails received inside Angel
Learning Assistants (LA’s):

undergraduate students who are statistics majors (or in a closely related major)

will also help in the computer lab meetings (not available outside the computer lab meetings)
HELP OPTIONS:
With large enrollment classes, students need to consider all possible help options. Two free options include:
Shared Office Hours (SOH)

Location: 220D Boucke & Dates: (Tues Jan 19 – Thurs Apr 28)

Conducted by a pool of graduate students from the statistics department

Hours are: (1-4 pm & 6-9 pm on Mon thru Wed) & (1-3 pm & 6-9 pm on Thurs)
Guided Study Groups (Through Penn State Learning) – start week of Jan 24

Guided Study Groups (GSG) is a collaborative learning program designed to support students, who
are enrolled in challenging larger lecture courses

GSG is a study group led by a trained student leader who is specific for this course

More info at https://pennstatelearning.psu.edu/study-groups
This course is a Lion Tutors/Nittany Note Free Zone. The instructor/ TA’s are not affiliated with and do
not provide any solutions for materials developed by external money-making sources such as Lion Tutors/
Nittany Notes. Such services only train you take an exam. These people are not statisticians. Consequently,
during the second-half of the semester, when the course material builds and becomes more challenging,
students struggle because they cannot integrate the old material with the new material. Do not: bring these
materials to office hours, show them to the instructor before or after class, or include them in any emails.
2
COURSE POLICIES:
In order for this large class to work both logistically and with fairness, certain policies must be in place for the
entire semester. With this course, you need to:

recognize that:
1. this is an in-residence course – can’t disappear for days/weeks expecting to make-up work
2. final grades are:
earned based on mastery of material (not on attendance or negotiations) - not changed for
financial aid and/or academic progress purposes. (also not curved or rounded) - individual
extra credit will not be allowed either during or after the end of the semester
3. lab activities & LAQ’s must be completed during the scheduled time in the assigned lab room
4. all exams, including the final, can only be taken at the scheduled time (can’t take early)
5. you must sign up for exams and follow all rules when using the Computer Testing Center
6. your iclicker must be: correctly registered & properly working (including good batteries)
7. instructor does not answer questions about grade calculations or clicker issues by email
8. you must seek immediate help if having problems
9. you must submit your own work

use Angel (with an acceptable browser and fully functioning internet connection):
1. to send email

under the “Quick Message” option (no response to emails received outside Angel)

with an acceptable greeting (includes a name), complete sentences, a subject line that
clearly identifies the purpose for the email & class identification by lecture time (Class 1 or
Class 2)
2. to regularly check:

the grade book right after making a submission (can’t report problems days/weeks/months
later) - Angel does not lose grades

all posted materials and emails

come to class: at the scheduled start time and willing to make the appropriate commitment (the
instructor does not post or provide filled-in lecture slides)

refrain from talking during class except as part of an activity as a matter of courtesy

Late Adds must contact the instructor within 24 hours of adding the course.
Academic Integrity:
Academic integrity includes a commitment to not engage in or tolerate acts of falsification, misrepresentation
or deception. Such acts of dishonesty violate the fundamental ethical principles of the Penn State
community and compromise the worth of work completed by others. This course will follow the Eberly
College of Science policy at http://science.psu.edu/current-students/Integrity/Policy.html
Disability Policy:
“Penn State welcomes students with disabilities into the University's educational programs. If you have a
disability-related need for reasonable academic adjustments in this course, contact the Office for Disability
Services (ODS) at 814-863-1807 (V/TTY), at 116 Boucke. For further information regarding ODS, please
visit the Office for Disability Services Web site at http://equity.psu.edu/ods/. In order to receive consideration
for course accommodations, you must contact ODS and provide documentation (see the documentation
guidelines at http://equity.psu.edu/ods/guidelines/documentation-guidelines).
Homework Quizzes & LAQ’s have already been adjusted to accommodate those who need additional time.
Electronics Use Policy: Research has shown that using an electronic device with a screen during class
distracts other students around you and hinders their learning**. To eliminate the screen distraction (halo
effect), we will have two different zones in the classroom to accommodate both behaviors.

Students who would like to be guaranteed a "screen free" environment should sit in the left half of
the classroom (as you are facing the front). Students sitting in this area have committed to not
using any electronic devices with a screen, of any size (laptop, phone, table, iPod, etc.) for the
duration of the class period. It is fine to use your devices before class starts, but students in this
zone have agreed to put them entirely away during the actual class time.

Students, who will be using any electronic devices that have any kind of a screen, or who don't
mind seeing others use such devices, should sit on the right half of the room. This applies
regardless of the reason the student is using the device. However, all students must still use
behaviors that show respect to all class members when using electronic devices.

This includes make-ups for any exam and the final.

For make-ups that are approved:
- work must be completed within three days of returning to campus/class
- under the same conditions/restrictions that was used by other class members
Lab Activity Quizzes & Homework Quizzes Make-Ups:

no make-ups under most circumstances because the course is front-loaded with drops

MOST IMPORTANT: with LAQ’s: everyone must use two drops (no exceptions) when sick,
have surgery, attend funerals, at court, family issues, personal problems, missed the bus, bad
weather, transportation/car issues, alarm on cell phone not working, work-related issues, Thon, etc.

It is not necessary to email the instructor about missing class with regard to these misses. Angel
will find the drops near the end of the semester.

Class will be held unless the university shut downs

extended illness/problems will be dealt with on an individual basis

quizzes will be available for practice after all students have submitted
Exams Make-ups:

only allowed if you have a University-related excuse or a religious conflict, you must talk to the
instructor in person and provide documentation with appropriate letterhead and signatures, prior to
the exam for arrangements.

Illnesses will be dealt with on an individual basis. Must contact the instructor by the exam day
about any unexpected illnesses, etc. All exams will be available for review after all students have
submitted

Exams, including the Final Exam, cannot be taken early (no exceptions)
GRADES:
Reported in the Angel Grade Book

based on points (not percent’s) - select “grades” with category under Repots

assessments linked to the grade book will show a grade of “0” until a submission is actually made

must check the Angel gradebook immediately after a submission/can’t report days or weeks later
about missing grades

Angel does not loose grades

Instructor does not answer emails about grade calculations or clicker issues
Final Grades: based on 1000 points

most importantly, grades are earned based on academic performance

point ranges for final grades are found in Table 3.

grade boundaries must be set so that student performances can be fairly evaluated

do not expect the grades to be curved (also cannot negotiate your grade or missed assignments at
the end of or after the semester is over).

will not be rounded. For example, a point total of 929.99 will be an A- grade, while a point total of
699.99 will be a D grade.

some class extra credit options are available during the semester to off-set policies that must exist
with large enrollment classes

no individual extra credit allowed either during or after the semester is over

LETTERS OF RECOMMENDATION:
Will only consider writing letters for students who:
 get to know me through several interactions (so that I can discover things to put in the letter)
 have a final grade of at least a B+ and when given 4-6 weeks of advanced notice
SOME HELPFUL TIPS:

The course requires both the acquisition of basic knowledge and conceptual understanding in
order to successfully solve challenging problems. Unfortunately, memorization only allows for
the acquisition of basic knowledge.

Many students don’t learn all of the material that we’ll see in this course the first time they are
exposed to it. So you can expect to do need several rounds of studying, trying, and evaluation
to master such material.

For enduring (deep) learning the three key components are: productive struggle, explicit
connections, and deliberate practice

Many studies have shown that multitasking is very detrimental to learning. When using this
practice to complete a task, it often takes longer and leads to making mistakes. Under these
conditions, the brain loses the capacity for deep thinking.

I see my job like that of a coach – I do my best to help, but ultimately the student plays a very large
role in his or her success. Thus, while I can help, ultimately learning is the responsibility of the
student.
 The three top reasons why students do poorly in this class: 1. don’t attend class, 2. don’t complete
the HW, and 3. become too dependent on Lion Tutors/Nittany Notes, etc.
