Final Exam Preparations

• 1) Final Exam: Content
  
  The final exam is comprehensive and will cover material from Chapters 1 to 7, 9, and 12 of the Moore/McCabe/Craig textbook. The following topics will not be tested in the final exam:
  
  • Parts of Section 4.5: "Bayes's rule" and "Independence again" (pages 301-302)
  • Entire Section 6.4: "Power and inference as a decision" (pages 401-410)
  • Parts of Section 7.1: "The power of the t test" and "Inference for non-Normal populations" (pages 435-440)
  • Parts of Section 7.2: "Software approximation for the degrees of freedom" and "The pooled two-sample t procedures" (pages 460-466)
  • Entire Section 7.3: "Optional topics in comparing distributions" (pages 473-481)
  • Entire Section 9.3: "Goodness of fit" (pages 545-548)
  • Parts of Section 12.1: "Inference for one-way analysis of variance" (attend lecture on Fr 12/10/2010 for details)
  • Entire Section 12.2: "Comparing the means" (pages 655-670)
    
    
  The final exam will consist of:
  
  • 30 multiple choice (MC) questions: 10 questions from online quizzes, 10 questions from past exams (final exams from past semesters and this semester's midterms), and 10 new questions. Numerical values and answer orders may be changed, so you need to know and understand the principle how each question can be answered.
  • At least one question from this semester's midterms (same principle, but new numbers) and some "shorter" questions related to Chapters 1 to 4.
  • Some "longer" statistical inference questions, such as sampling distributions, confidence intervals, and hypothesis testing, based on Chapters 5, 6, and 7.
  • Chapters 9 and 12 will be examined via MC questions only.
    
    
  Note: You will be given about 110 minutes to complete the final exam. The exam will be a closed-book exam, which means that you are not allowed to use the textbook or the lecture notes. You can only have one formula sheet (see below for details). All required tables (such as for the normal curve) will be provided. You should bring your calculator!
  
  The final will be comparable in length with previous finals. You have to work efficiently. Read carefully whether you have to "Show your work" or "Circle your answer" (and whether some further explanation is needed or not). Check solutions for old exams (midterms and finals) to determine how much of a calculation you have to write down to obtain full points in "Show your work" questions.
  
  
• 2) Final Exam: General Study Suggestions
  
  
  • Work through both of the posted old finals from Fall 2009 and Spring 2010 (in 2 hours each!).
  • Work through all old midterms (from our semester and past semesters) as about 50% of the final will be new material after Midterm 2, but about 50% will be material up to Midterm 2. Don't forget that I promised that at least one of our midterm questions will show up in the final in a modified form.
  • Work on the online quizzes (see below for additional details). As in the midterms, 1/3 of the MC questions will be taken from the online quizzes (possibly after modifying some values or changing the answer order).
  • Don't forget to look at the homeworks and homework solutions to avoid mistakes such as in Midterm 2 where many students overlooked that units are in thousands - and this was clearly stated in the HW solutions.
    
    
• 3) Final Exam: Preparation via Online Quizzes
  
  As part of your preparation for the final, go to the IPS6e Web Page at http://www.whfreeman.com/ips6e and work on the "Online Quizzes" for Chapters 5, 6, 7, 9, and 12. You can safely leave out questions that deal with content not discussed in class. Submit your answers via the "Submit" button at the bottom of the page. Carefully check which questions you answered correctly and which questions you answered incorrectly.
  
  Be warned that our actual final will reuse several of these questions - either as stated in the "Online Quizzes" or with some minor numerical modifications. You may also want to revisit the "Online Quizzes" for Chapters 1 to 4 as some questions in the final may also be taken from this pool of questions.
  
  
• 4) Formula Sheet
  
  In the final, you will be allowed again to use a formula sheet (1 sheet only, letter size, handwritten, text on both sides). This formula sheet can contain all useful information such as formulas, definitions, sample calculations, and solutions or solution outlines (from homeworks, past exams, the Web, etc.). Your name must appear in the upper right corner. There is no need to copy tables (such as the normal table, t-table, Chi-Square table, etc.) as those will be provided during the exam when needed. Before the final, add missing information from Chapters 5, 6, 7, 9, and 12 (as far as discussed in class) to your sheet - or create a completely new formula sheet that covers Chapters 1 to 7, 9, and 12.
  
  
• 5) Drop-in Tutoring during Final's Week
  
  The Drop-in Math & Stats Tutoring Center in the Taggart Student Center will be closed after Fr 12/10/2010 for the remainder of the semester. The Drop-in Tutoring at the Lundstrom Center will be closed after Th 12/9/2010 for the remainder of the semester. If you need additional tutoring, you should go to the Tutor Advertiser on the Academic Resource Center website.
  
  
• 6) Recitation Sessions during Final's Week
  
  Additional recitation sessions during Final's Week will take place as follows:
  
  • Mo 12/13/2010, 7pm-9pm, ENGR 104: Final exam review session, going over the Spring 2010 Final.
  • Tu 12/14/2010, 5pm-7pm, ENGR 104: Final exam review session, going over the Spring 2010 Final.
    
    
  There are no recitation sessions at the regular times on Tu 12/14/2010.
  
  
• 7) Final Exam: Time and Location
  
  The final will take place on Wed 12/15/2010, 7:30am-9:20am, in our usual classroom. In addition to your formula sheet, you are only allowed to use a stand-alone calculator. Immediately follow our seating rules that require you to align in columns and leave at least two unused seats between any two students.
