  2. Google Hangouts on Air

Textbook

The textbook for this course is a free online textbook located at: http://statistics.byuimath.com/index.php?title=Main Page. It is a modern introduction to the practice of statistics. It is written at the level of Sullivan's Statistics: Informed Decisions Using Data. The textbook is focused on interpretation and does not emphasize theoretical issues.

Course Schedule

This course has been designed to follow a weekly schedule in which students complete two lessons per week. You are expected to complete all of the learning activities for each lesson in the order they are listed. Also, you should complete each lesson in order and not skip ahead to the next week without finishing the previous week's assignments. The instructor may shift the order of completion for some assignments, and may even extend the deadlines on a few assignments if circumstances warrant it for the whole class.

Due dates and times for all assignments may be found by accessing the Calendar tool in I-Learn. In addition, all required assignments and tests have been set up to appear in the "Due Soon" list that you will see whenever you log into I-Learn. Also, all activity directions will have information on when the assignment or assessment opens and when it closes (due date and time). These due dates and times listed in the activity directions are based on Mountain Time in the United States of America, and are set up to be aligned with the due dates and times of students on campus at BYU-Idaho. If you have any questions about when an assignment is due, you should contact your instructor.

The deans at BYU-Idaho have determined that the average amount of study time that students will put in per week per credit is 3 to 4 hours. So, for a 3-credit class, the deans expect students to spend on average between 9 and 12 hours of total study time. For this course, on average, it will take students approximately 9 hours of study time to complete all the learning activities for each week. This is the amount of time that you should expect to put into this class each week if you want to get a passing (C) grade. If you want a higher grade, you may need to put in more study time, maybe even beyond 12 hours per week. Students working towards an A or B grade will usually need to put in more study time than 9 hours a week. Consequently, in order to keep up with the assignments and learn the most from this class, you should make sure you schedule about 1 to 2 hours a day to study for this class.

Course Navigation

You can access all materials in I-Learn. There are 24 lessons. We will complete two lessons per week. Each lesson contains three parts: (1) Individual Preparation, (2) Group Meeting, and (3) Homework.

Individual Preparation

You prepare for each lesson by studying the corresponding reading. We've prepared pre-structured notes which guide you through the key concepts and ideas for each particular lesson. The pre-structured notes have two parts. Part I asks you to define new terms and write down relevant formulas prior to completing Part II. In Part II you will complete practice problems where you have access to a key to check your work.

Group Meeting

You meet with your group twice a week after you complete your individual preparation. During the group meeting you'll do the following:

  • Start by joining your group on Google Hangouts.
  • Next discuss any questions you have from Part II of your individual preparation notes.
  • Take the Group Meeting Quiz together.
  • The first two questions on each quiz are:

T/F. I completed the Individual Preparation assignment before attending the Group Meeting.

T/F. I actively participated in this week's Group Meeting.

  • After you submit the quiz, your teacher will go over the results and provide feedback.

Homework

The homework contains two parts, an assignment and a quiz. In the homework assignment you can solidify your understanding of the concepts from the lesson. An answer key is provided, and you may rework the problems as many times as needed. When you finish the homework assignment you then take the quiz. You may only take the quiz once

Exams

There are four exams in the course that will be taken online in Brightspace (just like homework and group quizzes.)

Project

There is a project during the second half of the semester that you will be working on in groups.

Google Hangouts

In this course we will be using Google Hangouts On Air (HOA) for the class meeting. All students should actively participate. Each group will have a group leader. The group leader is responsible for recording the class meeting and then posting the link to the Group Collaboration Discussion Board that is found after each lesson. The instructor will spot check random group meeting links each week to watch for attendance and active participation.

Teaching Assistant

This course has a TA who will attend one meeting for two different groups each week (your group will be visited by the TA once or twice per semester), and will also be available for tutoring two hours a week. The instructor will let you know when the TA will be offering tutoring hours.

Grading

This course will use the standard BYU-Idaho grading scale:

A93-100%C73-76%
A-90-92%C-70-72%
B+87-89%D+67-69%
B83-86%D63-66%
B-80-82%D-60-62%
C+77-79%F0-59%

Grade Components

Grades will be determined as follows:

  • 60% Exams
  • 20% Homework
  • 10% Preparation
  • 10% Final Project

Course Policies

You should read the following course policies and make sure that you understand what these policies mean to you regarding your interactions with the instructor and other students in this course. If you have questions about any of these policies, you should contact your instructor immediately.

Personal Honor

In this class, our interactions with each other should be guided at all times by the following principles of personal honor.

Principles of Personal Honor - "True at all Times"

  • Personal honor is integrity in fulfilling commitments, responsibilities, and covenants.
  • Personal honor begins with willing obedience and is fully developed when we consistently govern ourselves by true principles.
  • Personal honor increases spiritual strength through the ministry of the Holy Ghost.
  • Personal honor is central to every aspect of our lives, including the BYU-Idaho experience.
  • Personal honor brings us joy and happiness; deepens our desire to love, serve, and lift others; and ultimately helps us to become more like the Savior.

You should make sure that you understand the above principles of personal honor. It is important for all class members to strive to follow the above principles in our associations with one another.

If you have any questions about how Personal Honor is related to academic honesty or the university's dress and grooming standards, you may visit the University Standards web page to get more information.

If you encounter unlawful sexual harassment or gender-based discrimination, please contact the Human Resources Office at 208-496-1700 or via email at humanresources@byui.edu.

Unformatted text preview: Statistics – Lab Week 4 Name: MATH221 Statistical Concepts: Probability Binomial Probability Distribution Calculating Binomial Probabilities Open a new MINITAB worksheet. We are interested in a binomial experiment with 10 trials. First, we will make the probability of a success ¼. Use MINITAB to calculate the probabilities for this distribution. In column C1 enter the word ‘success’ as the variable name (in the shaded cell above row 1. Now in that same column, enter the numbers zero through ten to represent all possibilities for the number of successes. These numbers will end up in rows 1 through 11 in that first column. In column C2 enter the words ‘one fourth’ as the variable name. Pull up Calc > Probability Distributions > Binomial and select the radio button that corresponds to Probability . Enter 10 for the Number of trials: and enter 0.25 for the Event probability: . For the Input column: select ‘success’ and for the Optional storage: select ‘one fourth’. Click the button OK and the probabilities will be displayed in the Worksheet. Now we will change the probability of a success to ½. In column C3 enter the words ‘one half’ as the variable name. Use similar steps to that given above in order to calculate the probabilities for this column. The only difference is in Event probability: use 0.5....
