GGC General Education Learning Outcomes

This course addresses the following general education learning outcomes:

II. Demonstrate critical and creative thinking

III.Demonstrate science literacy

V.Understand and effectively use information technology

GGC Mathematics Educational Goals:

Consistent with the overall goals of the General Education Program at Georgia Gwinnett College, students enrolled in mathematics courses at GGC should be able to:

Express mathematical ideas in both written and oral form. (*GGCGELO-III)

Demonstrate critical thinking and mathematical creativity (*GGCGELO-II)

Use and apply mathematics to better understand scientific, historical, and current national and global issues (*GGCGELO-II, III, V)

Use information technology effectively to mathematically analyze and solve real world problems (*GGCGELO-V)

The four educational goals are not independent.

*Addresses the GGC General Education Learning Outcome(s) specified.

Course Goals: Statistics is often referred to as the "art & science of data analysis."The purpose of this course is for students to understand statistical analysis by working with data. Statistical thinking involves the appreciation of variation and uncertainty, and their impact on decision-making.Students will apply the scientific method to issues and problems. Students who have completed this course have said the thinking required is similar to that in "critical thinking" or "logic." Studentswill experience the process of formulating questions, gathering data, analyzing the data, and interpreting results.Students will learn these steps by doing each of these parts separately and tying them all together.Throughout the semester, concepts will be stressed. After completing this course, students will be able to:

  • See statistical analysis as a practical and useful tool in today’s society. (*GGCMEG- 1, 2, 3, 4)
  • Understand that variability is natural, predictable, and quantifiable (*GGCMEG- 2, 3)
  • Know the parts of the process through which statistics works to answer questions. (*GGCMEG- 1, 2, 3, 4)
  • Choose the appropriate graph and analysis technique(s) to address research questions. (*GGCMEG- 1, 2, 3, 4)
  • Communicate the results of a statistical study in the context of the given scenario, including scope of inference and causality. (*GGCMEG- 1)
  • Use statistical language appropriately. (*GGCMEG- 1)
  • Use appropriate technology in the evaluation, analysis, and synthesis of information in problem-solving situations. (*GGCMEG- 4)

* Addresses the GGC Math Educational Goal(s) specified.

  • Chapter 1 Sections 1, 2, and 3
  • Chapter 2 Sections 1, 2, 3, 4, 5, and 6
  • Chapter 3 Sections 1, 2, 3 and 4

  • Chapter 11: Sections 1, 2
  • Chapter 12 Sections 1, 2 and 3
  • Chapter 14 Sections 1 and 2
  • Chapter 15 Sections 1 and 2

Assessment Tools/ Grading Policy:

A 10-point grading scale is used in calculating the grades.

Test Average40%89.5 – 100 = A

Homework Average10%79.5 – 89.5 = B

Quiz Average10%69.5 – 79.5 = C

“Mini” Project10% 59.5 – 69.5 = D

Final30%< 59.5 = F

Tests/Final: We will have 4 tests and a cumulative final during the semester. Although the tests are not cumulative, the material does build upon itself throughout the semester. In other words, you may need to use concepts from previously tested material. You should “clear up” any misunderstandings you have as early as possible. Problems on the test require you to make calculations as well as understand the meaning of concepts. The first three exams are closed book and closed notes, but you may use 2 sheets of 8.5”x11” paper front and back for notes for each exam. You can use your note sheets from previous exams. For example, on exam 2, you can have 2 new sheets for exam 2 plus the 2 sheets you used for exam 1 as well. As you view old copies of exams over WebCT, you will have a better sense of the exam structure. I will use the chapter objectives (listed at the beginning of the notes for a particular chapter) in developing exams. I do not believe any placing any “surprise” questions on the exam, but note there are many different ways I can state a problem that would test a particular objective.

Homework: Homework will include problems that you will calculate by hand as well as use the computer program: SPSS (Statistical Package for the Social Sciences). You may drop your lowest homework grade.

Quizzes: During the course of the semester, I will post several quizzes on WebCT. I will make the quizzes available for a 24-hour period. These quizzes will consist of 3 or 4 multiple-choice questions. You may drop your lowest three quiz grades.

“Mini” Project: In groups of 2-4 people, you will use SPSS to analyze “real world” data. Your group should select one of the data sets shown on to use during the course of the semester. During the course of the semester, I will ask your group to write periodic reports using SPSS to analyze your data set. In addition, each group member will submit a short reflection (1 page) describing how you might use the techniques to address a problem in your major. Your grade on each mini project is 20 points from your team member’s evaluation of your contribution, 30 points for your individual short reflection and 50 points for your team’s report.

Absence/Make-up Policy: Regular attendance is expected and necessary to understand the material. It is the students responsibility to initial the sign-in sheet every class period. If you are late, you are not allowed to initial the sign-in sheet. In addition, students are responsible for all work whether you attend class or not. The sign-in sheet will be used to assess grades in borderline cases. Student visits to my office (particularly seeking help as early as possible) can also positively affect borderline grades.

Academic Enhancement Center

The Academic Enhancement Center provides free drop-in tutoring for GGC students. Tutoring is available in many subjects including reading college texts, writing assignments, grammar focus, research and citation, college algebra, calculus, chemistry, and physics. The Academic Enhancement Center is located on the 2nd floor of building B in B 2400 and B 2450. The hours for the AEC can be found in Jovo (jovo.ggc.usg.edu) under the Support tab.
