Course Prerequisites

MATH 110 (College Algebra) is recommended.

A person taking Statistics without having taken College Algebra will find Statistics 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 includes College Algebra.

Course Materials

Summary: Students must purchase access to StatsPortal for course content. An electronic version of the textbook comes with it. Students will also need access to a scientific calculator.

Required Materials

After you have registered for the BYU Stat 121 Independent Study course through Independent Study, you will need to:

  1. Purchase access to StatsPortal either directly on the StatsPortal website or from the BYU Bookstore. The StatsPortal website is maintained by the publisher of the textbook Basic Practice of Statistics, and contains:
    • the e-book of Basic Practice of Statistics, 6th edition, by David S. Moore that supports highlighting and note taking
    • StatTutor, which includes the lecture videos you need to watch
  2. Register on the STAT 121 Moodle course website. This site is maintained by the Department of Statistics for the Statistics 121 course and is free of charge to the students. It contains:
    • all lesson instructions
    • credit quizzes and practice quizzes
    • exam preparation materials
    • other course materials and helps

NOTE: You will need to register for both the StatsPortal and Moodle websites. Go to the "Getting Started" section of this course for registration details.

  1. You will need to have a scientific calculator with a square root function.
    • For practice and credit quizzes, you can use any computational device.  However, for exams, you may use only a non-graphing (scientific) calculator.

Optional Materials

Overview of Course Requirements

Course Organization

Note: We strongly recommend that you complete all of the preceding assignments before requesting an exam. You will not be able to request Midcourse Exam 3 until you have completed both Writing Assignments. Before you will be able to request the Final Exam, all earlier work must be completed and the grade posted.

Lessons

All lesson instructions are found on the Moodle course website , as well as in the document “Statistics 121 Independent Study Lesson Outline.” Lessons on the Moodle course website are listed in chronological order and will guide you through each reading, viewing, practice and graded assignment.

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

  1. Read sections of the e-book on StatsPortal or in the textbook Basic Practice of Statistics, 6th edition, by David S. Moore.
  2. Watch the corresponding StatTutor videos on StatsPortal.
  3. After reading the textbook and watching the video(s), take the practice quiz. Review as needed and then take the credit quiz.

StatTutor Videos

All StatTutor videos are available on the StatsPortal 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 StatsPortal. To play these StatTutor videos, you will need QuickTime Player loaded on your computer. (It is a free download.) StatsPortal 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.

Assignments

Summary: 39 assignments (credit quizzes), 39 practice quizzes (optional, extra credit) are completed through the STAT 121 Moodle course website (a separate web application), and 2 written assignments. No resubmissions allowed.

WARNING: All credit quizzes and writing assignments are open book and open notes. However, taking a quiz for someone else, using answers provided by another student, having a tutor-type person help you take any quiz, etc. is cheating. Writing assignments with plagiarized answers will receive no credit.

Practice Quizzes on the Moodle Course Website

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 count as 2 percent of your course grade. These are extra credit.

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 and Writing Assignments

For each lesson, you are required to take a credit quiz. Your scores on the credit quizzes and writing assignments count as 15 percent of your course grade.

The credit quizzes are in your Moodle course and 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: Your credit quiz grades must be transferred to your Independent Study course gradebook once you’ve completed all quizzes on the Moodle course website and the writing assignments in your Independent Study course. You will do this right before requesting the final exam in the "Credit Quiz Grade Transfer Request" section of your Independent Study course. Your overall grade for the quizzes must be posted AFTER the last lesson, but BEFORE you can request your 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 before you take them. In addition, use your notes and textbook to correctly answer the questions.

Writing Assignments

There are 2 writing assignments; each is worth 1% of your total grade. The details of each assignment are contained within the assignments. The writing assignments are in your Independent Study course in the sections following the second exam.

Be sure you have taken ALL credit quizzes and completed the writing assignments associated with an exam before requesting that exam.

(Back to top)

Submitting Your Writing Assignments

You will submit your completed writing assignments to Independent Study through the appropriate Writing Assignment section of your Independent Study course.

There are several ways to access the writing assignments. One suggestion is to login to is.byu.edu, select your course (STAT 121), click on "Writing Assignment" and then "open," and upload your assignment there. You can also find the assignments in the lefthand menu of your Independent Study course.

There are a number of file formats in which you may submit your assignments: .rtf, .doc/.docx, and .pdf. For all of the formats, use the course number and section, your first and last name, and the assignment name for the filename. For example, if you are in section M001 and you have chosen to use the .rtf file format you would name it something like "STAT121-M001_KimJones_WritingAssignment1.rtf"—with your own name, of course!

Study Resources

Pre- and Post-Tests on the StatsPortal Website

Every chapter on the StatsPortal 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/e-book, 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 exercises as needed.

We recommend that you use a statistical software package to perform computations. StatCrunch requires the following password: BYUStat. Instructions are available under “Important Course Materials” on the Moodle course website. CrunchIt! is also available under the Resources tab on StatsPortal. Instructions are also found under the Resources tab.

Note: If you have trouble opening StatCrunch, you may need to adjust the Java settings on your computer. Click here for detailed instructions.

You may opt to use a graphing calculator such as the TI-83 or other statistical software such as Microsoft Excel instead of StatCrunch or CrunchIt! Using other statistical software is okay, but you will have to figure out the necessary commands on your own. Using StatCrunch, 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 StatsPortal website. In addition, you can click on any statistical term in the Basic Practices of Statistics e-book to get a definition. Glossaries of new terms you need to know for each exam are also available on the Moodle course website in each “Exam Preparation” folder.

Midcourse and Final Exam Preparation Guides

Exam preparation guides are available to help you study for each exam. These guides include a list of terms for which you need to know their definitions, computations you need to be able to do, identifications you should be able to make, and so forth. The guides are available on the Moodle course website in the preparation lesson for each exam.

On the last page of each exam preparation guide is a copy of the formula sheet that will be at the end of each exam. Here is a description of the formulas you should be able to use for each midcourse exam:

Practice Exams

Before taking a midcourse exam or the final exam, be sure to take the corresponding practice exam, as you will not be able to retake any exams. The practice exams are available on the Statistics 121 Independent Study Moodle website in the corresponding “Exam Preparation” folders. The answers to the practice exam questions are found on the last page of each practice exam.

The practice exams 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 exam questions to be duplicated on the midcourse exams. The exams focus on statistical terms, facts, concepts, and interpretation of results more than computations.

(Back to top)

Exams

Summary: 3 proctored, instructor-graded midcourse exams and 1 proctored, computer-graded final exam. A scientific calculator is allowed during exams; no graphing calculators. (No retakes allowed.)

NOTE: You will use the Midcourse Exam Request and Final Exam Request links in your Independent Study course to request the exams. (You will not be able to request them from your Moodle course.)

Midcourse Exams

There are 3 midcourse exams worth 55% of your grade. The first part of the midcourse exams consists of multiple-choice questions and matching questions. The second parts are 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 tutor 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 found in “Important Course Materials” at the top of the list of lessons on the Moodle course website. The formula page is also found at the end of every exam preparation guide as discussed above. 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 learn everything listed on its exam preparation guide. Then, take the corresponding practice exam. After you take the practice exam, check your answers and restudy the material corresponding to those questions that 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.

It is recommended that you schedule at least 3 hours to take Midcourse Exams 1-3 at your testing center.

Final Exam

The final exam is comprehensive and consists of multiple-choice questions with about 25 percent of the questions coming from each unit, including unit 4. The final exam has no essay portion and counts as 30 percent of your final grade.

Note about the final exam: You must earn a minimum of 55 percent on the final in order to pass this course. If you fail the final exam (that is, score below 55 percent), you can petition to retake it if there are extenuating circumstances.

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

IMPORTANT: You cannot request to take the final exam until:

  1. You have completed all 39 credit quizzes
  2. Your score has been posted to your Independent Study course gradebook.
    • You will do this through the "Credit Quiz Grade Transfer Request" assignment, which is where you will see your score.
    • This credit quiz score is permanent and cannot be changed later. So, be sure you have completed all the credit quizzes before you request the final exam!
  3. You have completed all writing assignments.
  4. 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 mailing time between when you complete an exam and when it arrives at the Independent Study offices to be processed.

To have your overall quiz score transferred from the Moodle course website to the Independent Study gradebook, complete the "Credit Quiz Grade Transfer Request" assignment in your Independent Study course. You can expect your overall quiz grade to be posted within 3 business days.

Remember, you must have your overall quiz score posted to your Independent Study course before you can request the final exam!
