Stat 200.7-9 Elementary Statistics - Penn State Department of Statistics

STATISTICS 200: SECTIONS 7-9 (SPRING SEMESTER 2014)
ELEMENTARY STATISTICS
HELLO AND WELCOME: The first thing that I want you to know is that 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 25 years at Penn State. This is one of my most
challenging and, at times, 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 while at Penn State. Statistics permeates life every day. I look
forward to facilitating your learning of statistics. Best wishes.

COURSE 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. You are strongly encouraged to read newspapers where you can
see how statistics can be applied to every-day life.
COURSE GOALS: The two overarching goals are to:
1. 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.
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
LEARNING GOALS: Be able to:
1. demonstrate how to summarize and interpret data: both with numbers and graphs
2. distinguish between population characteristics and sample information
3. understand the properties of and apply results found with distributions
4. correctly apply procedures to make statistical inferences about population characteristics
5. understand the core principles of both random sampling and variation
6. recognize the strengths and limitations of both sampling methods and study designs
