Course Description
This course is an introduction to mathematical statistics with an emphasis on statistical estimation and hypothesis testing. The course will be comprised of both theory and applications. We begin with a condensed review of fundamental concepts from Math 352; particularly, we briefly review important discrete and continuous probability distributions. We will then begin our discussion on the main topic of this course, statistical inference, through the study of distributions of functions of random variables using the method of moment-generating functions and order statistics. We then discuss ideas of convergence with sampling distributions and the central limit theorem. Next, we consider the topics of estimation, properties of point estimators, and methods of estimation. Finally, we study the theory of statistical tests and likelihood ratio tests. Depending on time, other topics may be added or removed.
Learning Outcomes
- Demonstrate statistical knowledge and apply it to various data sets.
- Use basic principles of statistical inference (both Bayesian and frequentist).
- Build a starter statistical toolbox and discuss the utility and limitations of these techniques.
- Use software and simulation to do statistics.
- Demonstrate ability to discuss statistical information in oral and written form.
Required Texts
- Modern Mathematical Statistics (MMS) with Applications, by Jay L. Devore and Kenneth N. Berk , Second Edition, Springer, 2021. (available online for free through the Broome Library).
Course Grading
| Category | Percentage |
|---|---|
| Homework | 25% |

At the end of the quarter, course grades will be assigned according to the following scale:
| A+ | 98 – 100 | B+ | 87 – <90 | C+ | 77 – <80 | D+ | 67 – <70 | ||
| A | 93 – <98 | B | 83 – <87 | C | 73 – <77 | D | 63 – <67 | F | < 60 |
| A– | 90 - <93 | B- | 80 – <83 | C– | 70 – <73 | D– | 60 – <63 |
Homework
Homework will be assigned on a regular basis and posted on https://m453.inqs.info/hw.html and CANVAS. All homework assignments are due at the beginning of class. The homework is to help you practice the concepts learned in lecture and to help you study. You must turn in your own individual homework and show your understanding of the material. At the end of the semester, the three lowest homework grades will be dropped.
Exams
There will be three exams and Final.
Exam #1 will most likely be during the 6th week of the semester. Exam #2 will most likely be during the 11th week of the semester. Exam #3 will be on December 9, 2024 10:30 AM - 12:30 PM.
While the exams are not considered cumulative, the material builds on each other. Developing a strong understanding of the material through out the course is important for your success.
At the end of the semester, your lowest exam grade will be replaced by your median average exam grade.
This course will operate under a zero-tolerance policy. Talking during the time of the exam, sharing materials, looking at another students’ exam, or not following directions given will be subject to the
University’s academic integrity policy.
Extra Credit
There will be 4 extra credit opportunities worth a total of 10% of your overall grade. (There are no make-ups for missed extra credit assignments!) More information will be provided on the extra credit assignments on a later date.
Class Schedule
The following outline may be subject to change. Any changes will be announced in class.

University Policies
Academic Honesty:
Please conduct yourself with honesty and integrity. Do not submit others’ work as your own. For assignments and quizzes that allow you to work with a group, only put your name on what the group submits if you genuinely contributed to the work. Work completely independently on exams, using only the materials that are indicated as allowed. Failure to observe academic honesty results in substantial penalties that can include failing the course.
Disabilities:
If you are a student with a disability requesting reasonable accommodations in this course, you need to contact Disability Accommodations and Support Services (DASS) located on the second floor of Arroyo Hall, via email accommodations@csuci.edu or call 805-437-3331. All requests for reasonable accommodations require registration with DASS in advance of need: https://www.csuci.edu/dass/students/apply-for-services.htm. Faculty, students and DASS will work together regarding classroom accommodations. You are encouraged to discuss approved.
