## Course Prerequisite

MATH 110 (College Algebra) is recommended.  A person taking Stat 121 without having taken College Algebra will find the course much more difficult than those who have. Statistics 121 requires students to be able to solve story problems and interpret the results in context.

Note: Pre-calculus or a full year of Trigonometry in high school can substitute for College Algebra.

## Course Materials

You will need these materials to complete the course.

1. David S. Moore, William I. Notz, and Michael A. Figner, Basic Practice of Statistics, 7th edition, Macmillan Learning (etext with Launchpad access). ISBN: 978-1464180828.

## Student Learning

You are ultimately responsible for your own learning. You can take charge of it by staying current with assigned readings and homework, attending the virtual lab sessions, and asking questions. Learning statistics requires focus and concentration!

You are accountable for learning the assigned materials. Spend at least 2 hours of personal study for each online lesson and at least another hour doing the practice and credit quizzes. Be aware of your learning style and monitor your class progress regularly.

## Overview of Course Requirements

• Complete all 39 credit quizzes and two writing assignments, which comprise 15% of your grade.
• Take three midcourse exams worth 55% of your grade. The first part of Midcourse Exams 1 through 3 consists of multiple-choice, true/false, and matching questions. The second part is the written portion.
• Take the comprehensive final exam which is worth 30% of your grade. The final has no written portion.

### Lessons

All lesson instructions are found in the course website.

For each lesson, you are asked to do the following:

• Read assigned sections of the e-book and watch the corresponding StatTutor videos on LaunchPad OR read the assigned pages in the textbook Basic Practice of Statistics, 7th edition, by David S. Moore.
• Watch the posted virtual lecture.
• Take the Practice Quiz.
• Review as needed and then take the Credit Quiz.

## Assignments

### Practice Quizzes

Each lesson has a practice quiz to make you aware of the important concepts in that lesson and to check whether you have mastered the material. Your scores on the practice quizzes can count up to 2% of your course grade. These are extra credit points added to your overall course grade.

Taking the practice quiz without notes or the textbook is recommended, but you are welcome to use them. Getting help from others is also acceptable on practice quizzes.

Each practice quiz consists of multiple-choice and true/false questions. Some of these questions require the use of a basic calculator and/or statistical tables. Understanding the correct answers for all practice quiz questions will help you prepare for the credit quizzes and exams.

Note: You cannot retake practice quizzes for this course. Complete feedback is given for every question after submitting each practice quiz.

### Credit Quizzes

For each lesson, you are required to take a credit quiz. Your scores on the credit quizzes and writing assignments count as 15% of your course grade. The credit quizzes are open book and open notes with no time limit, but getting help from any other person is not acceptable. Receiving assistance from another person on any credit quiz is considered cheating and could result in failure in the course.

Like practice quizzes, credit quizzes consist of multiple-choice and true/false questions, and some of the credit-quiz questions require using a basic calculator, statistical tables and the STAT 121 formula sheet.

IMPORTANT: All credit quizzes must be completed before you request the Final Exam. Please plan your study schedule accordingly!

Note: You cannot retake credit quizzes for this course because complete feedback is given for each question after you submit each credit quiz. Use the practice quiz questions, StatTutor lessons, and textbook/e-book exercises to prepare for the credit quizzes. In addition, use your notes and textbook to correctly answer the questions.

### Writing Assignments

There are two writing assignments. The details of each assignment are contained within the Writing Assignment folders. The Writing Assignment 1 folder follows Lesson 19 and Writing Assignment 2 folder follows Lesson 27.  Writing assignments are open book and open notes, but writing assignments with plagiarized answers will receive no credit.

### StatTutor Videos

All StatTutor videos are available on the LaunchPad website. You can access them in two ways: either by clicking on the StatTutor icon in each section of the e-book (with the exception of some chapter introductions), or under the Resources tab on LaunchPad. To play these StatTutor videos, you will need QuickTime Player loaded on your computer. (It is a free download.) LaunchPad automatically gives the link for the download when you click on the StatTutor icon.  A few StatTutor videos have two or three parts, which are indicated in the lesson outline.

### Study Resources Pre- and Post-Tests

Every chapter on the LaunchPad website has a personalized study guide. The study guides contains chapter pre-tests and post-tests. Use these tests as needed to gain better understanding of the material.

### Textbook Exercises

In the Basic Practices of Statistics textbook/ebook, the exercises are given at the end of each section and at the end of each chapter. Answers are given for all odd-numbered exercises. Do these exercises as needed.

We recommend that you use a statistical software package to perform computations. CrunchIt! can be accessed under the Resources tab on LaunchPad.  Instructions on how to use CrunchIt! are found under the Resources tab of LaunchPad.

You may opt to use a graphing calculator such as the TI-83 or other statistical software such as Microsoft Excel instead of CrunchIt! Using other statistical software is okay, but you will have to figure out the necessary commands on your own. Using CrunchIt!, a graphing calculator, or other statistical software will save you a lot of time. But remember, buying a graphing calculator is not necessary—it’s just an option and you won't be able to use it on your exams. All that is needed is a scientific calculator with a square-root function for practice quizzes, credit quizzes, and midcourse exams. (You will not be asked about software commands on exams or credit quizzes.)

### Glossary

A complete glossary of all the terms in this course is available on the LaunchPad website. In addition, you can click on any statistical term on the LaunchPad lesson sections to get a definition.

## Exams

### Practice Tests

Before taking a midcourse exam or the final exam, be sure to take the corresponding practice test, as you will not be able to retake any midcourse exams. The answers to the practice test questions are found on the last page of each practice test.

The practice tests will give you a good idea of the types of questions that will be on the midcourse exams and the final. Do not expect the practice test questions to be duplicated on the midcourse exams. The exams focus on statistical terms, concepts, and interpretation of results more than computations.

### Midcourse Exams

There are three midcourse exams and together they are worth 55% of your grade. The first part of each midcourse exams consists of multiple-choice questions and matching questions. The second part consists of short essays. All midcourse exams and the final exam must be proctored. All are closed book and closed notes, but have no time limit.

After taking any exam, discussing anything on the exam with anyone other than the course instructor or the Independent Study Statistics tutors will result in you failing the course.

A page of formulas and a page of tables will be supplied with each exam. Copies of both the “Stat 121 Tables” page and the “Stat 121 Formulas Sheet” are posted on the Exam folders. You will also need a basic calculator to use while you take each midcourse exam and the final exam. Please bring one with you. (Remember, you cannot use a graphing calculator on exams.)

To prepare for each midcourse exam or final exam, make sure that you view the Exam Review PowerPoint slides and take the corresponding practice test. After you take the practice test, check your answers and restudy the material associated with those questions you missed. Reviewing the practice quizzes and credit quizzes will also help.

Be sure that you are ready for an exam before scheduling it because there are NO midcourse exam retakes. Further, a midcourse exam cannot be taken until all of the credit quizzes associated with the units covered on that exam have been completed.

• Midcourse Exam 1 covers Lessons 1-13.
• Midcourse Exam 2 covers Lessons 1-23.
• Midcourse Exam 3 covers Lessons 1-33.

It is recommended that you schedule at least 2 hours for each midcourse exam at your Testing center.

### Final Exam

The final exam is comprehensive and consists of multiple-choice questions. It has no essay portion and counts as 30% of your final grade. It is recommended that you schedule at least 3 hours to take the final exam.

As with the midcourse exams, if you discuss anything on the final exam with anyone other than the course manager or the Statistics tutors, you will fail the course.

IMPORTANT: You cannot request the final exam until:

• You have completed all 38 credit quizzes
• You have completed all writing assignments.
• You have completed and received a posted grade for all previous midcourse examinations. If you are on a deadline to finish the course, this means you must allow for sufficient time between when you complete an exam and it is graded.

Note about the final exam: You must earn a minimum of 55 percent on the final in order to pass the course.
