STAT 100: Elementary Statistics and Probability
Fall 2013
Course Goals
1. To expose the student to the ideas and concepts of statistics and probability.
2. To enable the student to master the concepts, methodologies, techniques and tools for collection of data, organization of data, and analysis of data to solve typical problems.
3. To enable the student to:
§ understand a problem and recognize the type of issue(s) and/or the kind of analysis required;
§ formulate the problem quantitatively;
§ associate the appropriate probabilistic models and statistical techniques;
§ understand and interpret the model results and obtain the required solution to problems using a statistical package (MINITAB for Windows).
4. To enable the student to communicate and present statistical results and inferences.
5. To provide a sound basis in statistics for the student’s future academic and professional careers and personal life.
Course Description
This course will cover chapters 1-10 and 13 of the text. The main topics include: organizing and displaying data, measures of central tendency and variation, probability and probability distributions, sampling distributions, confidence intervals, and hypothesis tests.
Materials Needed
You will need to purchase:
● Access code to WileyPlus, the online homework system
● Calculator (must do basic arithmetic operations and take square roots)
You will need access to or purchase
● Textbook: Statistics: Principles and Methods, 6th Edition, by Johnson and Bhattacharyya.
● MINITAB
If you purchase WileyPlus, you will have the online version of the book (e-book). You will only have one year access to the e-book. So if you would like the hard copy of the book, it may be to your advantage to purchase the hard copy of the book and the access code to WileyPlus as a bundle.
There will be Homework Assignments and MINITAB Assignments found on WileyPlus (see the Assignments section below for more details).
Technology Requirements
You are required to master a variety of technologies as a part of this course.
You must be able to navigate and use a computer.
You must purchase an access code so that you are register for your section in WileyPlus. You must be able to maneuver in the WileyPlus environment because your homework assignments will be completed and submitted online electronically. And your MINITAB Assignments will be downloaded from there.
You must demonstrate competence in the use of the MINITAB statistical software system. This includes but is not limited to the following: properly installing the software on your own computer (if you choose to do so) or understanding how to access the software on University of Maryland computers (MINITAB is installed in the Department computer lab (room 0203 MTH) and in most WAM labs on Campus); understanding how to use MINITAB; understanding how to create “professional” style graphics and how to insert those graphics into your MINITAB assignments.
You must demonstrate competence in the use of a word processor such as Microsoft Word. In particular, you must be able to import graphics from MINITAB, create a report, and print it.
You must demonstrate the ability to manage files and use the Internet.
A calculator will be needed (any calculator as long as it can do basic arithmetic operations and can take square roots). .
Important Information about How We Present Information to You
We will present information to you in several different ways. Some information is contained in the textbook for this class. This may be the only source of this information. You must read and study the text to absorb this information. Some information is presented in class only. You must attend class and listen carefully to your professor to absorb this information. Some information might be given in the answers to your homework problems only.
Regardless of the manner by which we convey the information to you, you are responsible for
its application for homeworks, quizzes, and tests.
You are expected to attend all lectures, work on homework, and participate in classroom discussion. We are not responsible for any information missed due to your absence.
Students are expected to read the chapters before the scheduled lecture dates.
Assignments
You will have Homework Assignments and MINITAB Assignments.
Exercises from the text are to be done online using WileyPlus. An access code comes with the text if purchased as a package (text and WileyPlus) or can be purchased the access code separately at their web site www.wileyplus.com. Students must register using the a URL given to you by your instructor. Do not use any other URL than this. Unless otherwise specified, each week's online homework will be accessible from Monday through the following Monday.
Homework Assignments will be assigned almost every week (sometimes more than one, especially during the summer session). Homework Assignments will be available and must be completed using the WileyPlus. Your answers are submitted electronically through the WileyPlus which will be due at a designated time. All late homework will have an automatic 30% reduction. (That is, if your homework had no mistakes, you will receive a 70 instead of 100 if assignment is submitted late.)
You also have MINITAB Assignments. For MINITAB Assignments you are required to type all homework solutions. That is, you must integrate in a word processor the MINITAB commands used to solve some the problem, the MINITAB results (including any graphs) used to solve the problem, and all written answers you provide. You will use the “copy and paste” features of Windows to accomplish the required integration of material. You must print out MINITAB assignments and submit them in class before the lecture begins. Please make sure your submission is stapled with your name on your assignment. (Points will be taken off if paper your paper is not stapled and/or your name is not present).
There will be a 5 point deduction each day your MINITAB is late (each day, not class period). After a week, a zero will be given.
You have at most a week after a homework assignment or MINITAB assignment is returned to question a grade. If you do not notify the instructor within that time, then the posted grade stands.
Quizzes and Tests
Quizzes:
There will be quizzes approximately every week (sometimes more than one, especially during the summer session). Quizzes are approximately fifteen minutes in duration.
Tests:
There will be two tests and a final exam. You should bring a calculator (cell phones and computers are not acceptable during tests and the final), a Study/formula sheet (8X11 front and back, handwritten formula sheet), tables which can be downloaded, and #2 pencil with eraser. You are not allowed to use other materials, including scrap paper.
If you cannot take a test before the test is handed back, then your final exam grade will be used as that test grade.
You have at most a week after a quiz or test is returned to question a grade. If you do not notify the instructor within that time, then the posted grade stands.
TESTS ARE CLOSED BOOK.
Policies
Prerequisites: Satisfactory score on Math Placement Exam or Math 110/ or higher.
Homework Due Dates and Times:
All Homework assignments should be submitted electronically in the WileyPlus and will be due before the class begins if during the week and by Midnight if due on Sunday. MINITAB will be collected at the day it is due before class begins.
Office Of Disability Services
