## Chapter 5 Objectives (Skills)

• Construct a histogram for a small dataset.
• List and describe two types of distributions for a histogram.
• Identify from a histogram possible outliers of a dataset.
• Construct a stemplot and/or dotplot for a small dataset.
• Calculate the mean of a set of data.
• Sort a set of data from smallest to largest and then determine its median.
• Find the mode (if it exists) of a dataset.
• Find the range of a dataset.
• Determine the upper and lower quartiles for a dataset.
• Calculate the five-number summary for a dataset.
• Calculate the standard deviation of a small dataset.

## Quiz 3 Chapter 5 (Sakai-> Tests & Quizzes)

• The quiz for Chapter 5 will be available from 12:00am Feb. 24 - 11:55pm Mar. 9.
• The quiz will consist of 10 multiple choice questions.
• You will have a maximum of two hours to complete the quiz.
• You will be allow two tries. The computer will accept the best score.
• Failure to take the quiz by 11:55pm Mar. 9 will be given a zero. No exceptions!

## Textbook Homework Problems (Practice/Not Graded)

The 9th or 10th edition of the textbook can be used for this course. All material covered is the same and independent of textbook editions. Homework problems between editions are the same.
 9th ed. 2, 3, 4, 9, 13, 14, 22, 34 pages 198 - 203 10th ed. 4, 5, 6, 13, 17, 18, 26, 38 pages 224 - 233

## Chapter worksheets (Sakai -> Assignments)

• Due by 11:55 pm Friday Mar. 2
• Use the Assignments tool to submit worksheet.

## Discussion Topic (Sakai-> Forums)

You will be required to participate in the discussion groups, i.e. Forums. The forums are aligned with the Learning Outcomes to provide practice and feedback and assessment for outcomes 3 and 4.

• The distribution of income in the United States is skewed to the right. According to a US Census Bureau report, the mean and median incomes of American households were \$56,000 and \$79,000 in 2016. Which of these numbers is the mean and which is the median? Explain your reasoning. Which of these numbers (mean or median) are better to use when talking about the average US income? Give another example where there is a large difference between mean and median. Give examples when it is better to use mean and when it is better to use median.
• Discussion for Chapter 5 will open at 12:00 am Saturday Feb. 24
• You are required to participate in the discussion boards.
• Discussion topic will end at 11:55 pm Friday Mar 9.
• See the syllabus on the grading rubric for discussions.

## For All Practical Purposes

The textbook for the course can be either 9th or 10th edition.

Videos and lecture notes are based on the 9th ed. textbook. The 9th or 10th edition of the textbook can be used for this course. All material covered is the same and independent of textbook editions. The course does NOT use any material/resources form the Publisher's online system LaunchPad.

## Student Resources (Publisher)

Math Applets and suggested websites are very helpful resources.

## URI General Education Course

General Education program 2016 (GE): This course fully satisfies both the general education Knowledge area A1: Scientific, Technology, Engineering, and Mathematical Disciplines (STEM) and Competency area B3: Mathematical, Statistical, or Computational Strategies (MSC).
General education program 2001 - 2015 (MQ): This course satisfies the general education requirement for Mathematical and Quantitative Reasoning.

## Course Description

LEC: (3 crs.) Introduces students to the spirit of mathematics and its applications. Emphasis is on development of reasoning ability as well as manipulative techniques. (Lec. 3/Online) Not open to students with credit in MTH 106 or MTH 109 and not for major credit in mathematics. (MQ)/(GE)

## Course Goals

The goal of this course is to prepare you for the mathematical and analytical aspects of the world around you, and to help you develop a stronger, deeper mathematical knowledge. This course is intended for students majoring in the liberal arts or other fields that do not have a specific mathematical requirement.

here is help available from the Academic Enhancement Center (AEC). For more information on AEC services visit the AEC website at http://web.uri.edu/aec/ .

## Special Needs

Any student with a documented disability should contact your instructor early in the semester so that he or she may work out reasonable accommodations with you to support your success in this course. Students should also contact Disability Services for Students: Office of Student Life, 302 Memorial Union, 401-874-2098. They will determine with you what accommodations are necessary and appropriate. All information and documentation is confidential.

University of Rhode Island regulations concerning incomplete grades will be followed. See University Manual sections 8.53.20 and 8.53.21 for details.

## Religious holidays

It is the policy of the University of Rhode Island to accord students, on an individual basis, the opportunity to observe their traditional religious holidays. Students desiring to observe a holiday of special importance must provide written notification to each instructor.

## Makeup Policy

Assignments, quizzes, and discussions are available for multiple days. Deadlines are given on all assignments. Missed deadlines will require documentation and the University Manual sections 8.51.10 to 8.51.14 will be followed.
