Final Exam Procedures

Exam overview and timing

  • The final exam is a comprehensive two-hour assessment (exactly 120 minutes).

  • It covers the full scope of the course, with an approximate emphasis of:

    • Post-Exam 2 material: ~60%

    • Early-course material: ~40%

  • You may fill out the front page before the exam starts.

  • During the exam, write your name on every odd numbered page. This cannot be done after time is called.

Exam format

  • The exam begins with objective questions:

    • Approximately 5–10 True or False questions, 2 points each

    • Approximately 4–10 Multiple Choice questions, 3 points each

    These questions will mix post-Exam 2 and earlier material.

  • The remaining questions are free response.

  • Unless stated otherwise, report numeric answers to four decimal places.

Graphs, work requirements, and interpretation

  • If graphs are needed, they will be provided, except you may be asked to draw or complete a modified boxplot.

  • All provided graphs will be labeled appropriately.

  • It is acceptable to use graphics to support your answers when appropriate.

  • Any numbers you use that are not provided in the question (and not computed in a prior part) must have supporting work shown.

  • A correct answer without work is considered incorrect.

Code recognition

  • You will not be required to write code.

  • You will be required to recognize code and interpret output.

Allowed materials

  • Two 8.5 × 11 inch crib sheets are allowed.

    • You may use both sides of both pages.

    • They may be typed or handwritten.

    • You may include anything you want.

    • Strong recommendation: organize for quick lookup (for example, headings, boxed sections, and color coding for formulas, definitions, theorems, and techniques).

  • A scientific calculator is required.

  • A z table is not needed. Any critical values or quantiles you need will be available from code output.

Desk policy and personal belongings

  • The only items allowed on your desk are:

    • crib sheets

    • writing utensils and erasers

    • scientific calculator

    • picture ID

  • All other personal belongings must be stored away (backpack, purse, etc.).

  • Once the exam begins, you may not open your bag unless given permission by your instructor.

  • If you need scratch paper, raise your hand and it will be provided.

    • Write your name in the upper right corner of all scratch paper.

  • Your phone must be stored away and cannot be at your desk.

  • You may not share anything with anyone else in the room.

Submitting the exam

  • Turn in your exam at the location assigned by your instructor.

  • You must show your PUID (or another ID with instructor permission) and sign the attendance sheet for your section indicating you took the exam.

Grading policy: consistency across parts

We grade on consistency, meaning your work on earlier parts affects how later parts are graded.

  • Positive impact (partial credit through consistency):

    • If a later part depends on an earlier computed value, we will grade the later part using your earlier answer, even if the earlier answer was incorrect.

    • This can allow you to earn full credit on later parts if your work is consistent.

    Example: If Part (a) asks for a normalization constant and Part (b) uses that constant to compute a probability, Part (b) can receive full credit if it is computed correctly using your Part (a) value.

    Important: If you are unsure on an early part, write something plausible so later parts can still be graded. However, an impossible value (for example, one that would make a density negative or identically zero) will reduce credit on dependent parts.

  • Negative impact (loss of points for inconsistency):

    • If you set up the problem one way and later proceed in a way that conflicts with your earlier setup, you can lose points even if the later computation is otherwise correct.

    Example: If you state a two-sided alternative hypothesis (≠) and later compute a one-sided confidence bound instead of a two-sided confidence interval, you will lose points for inconsistency with your earlier setup.
