COURSE OVERVIEW:

Welcome to Stat 200. In today’s world, we are seeing a major trend throughout both industry and government where decisions are data-driven. Statistics is a discipline dedicated to unraveling the mystery of making such decisions in the face of 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. 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. explore the scientific method from a statistical perspective

- includes being able to identify questions, collect evidence, discover and apply tools needed to interpret the data, and communicate results. While many of you may never conduct a scientific study, it is still very 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 use to make good decisions

LEARNING GOALS : Be able to:

1. appropriately summarize data: both numerically and graphically

2. distinguish between population characteristics and sample information

3. understand the behavior of both distributions and sampling distributions

4. correctly apply procedures to make statistical inferences about population characteristics

5. identify the assumptions required for the validity of a statistical inference

6. recognize the strengths and limitations of both sampling methods and study designs

7. use computer software to find quantitative solutions when possible

COURSE AGREEMENT:

This syllabus serves as an agreement that begins on the first day of class & ends upon completion of the final exam. With this course, you need to:

 accept that:

1. this is an in-residence course – don’t disappear for days/weeks expecting to make-up the work

3. grades will be based on mastery of material (not on attendance)

4. individual extra credit will not be allowed

5. during class only use cell phones for emergencies (no constant texting)

6. prepare for lab in advance so that you can complete activity and quiz during scheduled time

7. the final exam must be taken at the scheduled time (don’t make plans to leave early)

 use Angel:

1. with an acceptable browser and wired connection

2. to send email;

 using the

“Quick Message” option (no response to email received outside Angel)
