Textbook: Introduction to Design and Analysis of Experiments Author: George W. Cobb; ISBN: 9780470412169 Course Website: https://ccle.ucla.edu Course Description: This course will introduce you to the practical and the theoretical underpinnings of the design of experiments. The practical aspect of the course deals with the design of interventions, sample size considerations, and power. The theoretical aspect of the course deals with the mathematical underpinnings of each design, the relevant assumptions that need to be met, interpretation of printouts and how they relate to the mathematical underpinnings of each model. Prerequisites: Stat 101A. In order for you to follow the discussions in this class, you should be familiar with the following concepts and calculations: • Basic concepts of descriptive statistics including the mean, median, variance, and standard deviation. • Sampling distribution, the Central Limit Theorem, the normal distribution, and Student's t-distribution, chi-square and F distributions. • Basic concepts of inference and hypothesis testing. Software: G-Power and R-studio. Both are Free software. You have two options (1) a desktop version that will require that you have a dedicated computer, or (2) the internet version, which can be accessed from any computer with an internet connection. 1. For the desktop version go to www.rstudio.org. 2. For the internet version, follow these steps: • Get a gmail account or make sure you know your current gmail address. • Send email to Josh Paulson at [email protected] and include your full gmail address: [email protected]. • Check to see that you have received a welcome email once your account has been set up. 1

NO LATE HOMEWORKS WILL BE ACCEPTED. NON-PDF HOME-WORKS WILL NOT BE GRADED. NO EXCEPTIONS!!!! Each homework assignment will be graded out of 100 points. Four randomly selected questions will be graded on a 20 point scale. 20 points awarded for a mostly correct answer with a few minor mistakes. 10 point awarded for a serious attempt with some mistakes. 0 points for a problem not attempted and/or serious mistakes. The remaining twenty points will be for the completion of the remainder of the problems in addition to clear, concise answers (not necessarily correct; just attempted). If your homework is messy, unorganized and hard to follow points may be deducted from these remaining 20 points. Homework can be done together (The technical part) but each student must turn in their own written assignment in his/her own words. UCLA policy is that you each do your own work to turn-in. Even homework assignments that have very similar wording to someone else will be flagged as possible plagiarism. This is a very serious offense at UCLA. Problems relating to The Island (discussed later in the syllabus) will have some amount of randomness so you will not get the same results as your classmates. Articles (Part of Homework): Some articles are assigned for you to read, in order to expose you to a peer-reviewed published articles that have experimental/observational designs for you to analyze and comprehend. A summary of the basic elements of the assigned articles will be included in your report. The assigned articles also are used as an inspiration for your group project using the island residents to apply your experimental design on them.

Midterm: There will be one midterm (week 5) on Friday, February 9th during regular lecture time that will cover the material from the first five weeks of the course. This will largely cover chapters 4 - 8 in the textbook (depends on our pace in this class). The midterm will be worth 20% of your final grade. This will be discussed later on in the course. Final Examination Code: March 21, 2018 Wednesday 11:30am-2:30pm (Cumulative) counts for 20% of your final grade. Final Project: You will be expected to work in groups of 2-3 (preferably 3 due to the large number of students allowed in this year) to make an in-class presentation(s) and write a final report to describe and summarize experiments that your group has designed and implemented on inhabitants of The Island. There will be various check-points throughout the quarter to keep your group on task and various methods of assessment of your contributions to your group in addition to the quality of your overall project. Island Life: You have been granted a visa to conduct research on Island, a recently discovered civilization somewhere in the Pacific Ocean, close to Australia. The Islanders have been isolated for many years, but you will have the opportunity to conduct experiments on the Islanders. You can visit the island at http://island.maths.uq.edu.au/index.php An email is going to be sent to you on week one in order to get access to the Island. I'll be using your email address listed on ccle. The following is the timeline of the different checkpoints for the final project, the short description of each checkpoint, and the grade breakdown of this final project. Each of these will have their own in-depth description and grading rubric posted to CCLE at a later date. If a deadline is missed 50% will be taken off from each of these grades for each day, it is late. • 01% - Group Formation and Initial Project Description (End of Week 2, January 19, 2018): Form your groups of 2 or 3 and write an initial introduction to your thoughts about the project. Make some decisions about your research question, variables of interest, and data collection. • 05% - Design and Protocol (End of Week 6, Friday February 16, 2016): Finalize your design procedures, collect your data, do some exploratory data analysis, outline the analysis that will be completed. • 02% -Sample Size Determination: You need to use G-Power or any other software to determine the sample size needed for your experiment with the islanders. • 05% - Presentation and Abstract (Weeks 9 and 10): - You will be randomly assigned to present your experiment one of 2 classes days during weeks 9 and 10. This will be a short presentation quickly outlining your research question, your data collection, and results. All slides and abstracts will be due 11:50 PM Sunday night (March 18, 2018). • 02% - Assess other groups (Week 9 and 10): - You are expected to assess other groups presentations on days when you are not presenting. This will hold your accountable to both give a good presentation as other people must understand your study and so you support your fellow classmates in their presentations. • 10% - Written Report and Island Activity (Thursday March 22, 2018): Prepare a final report of your entire study. This will be due the Thursday evening 11:50 PM of the finals week. 3

• If you forget or failed to take a quiz, Homework or exam at the specified time posted on ccle or listed in your syllabus, it cannot be made up and it will be counted as zero. Please do not Email me about it. Incomplete: To receive an incomplete grade, you must have completed at least 75% of the total grade with a minimum of C average. Students are not allowed to switch between lectures or sections during the quarter. If a student does that, he/she will have no credit for attendance, quizzes, homework and exams.

The lifetime of reviewing any graded assignments of exam is 5 days once the grade is posted on my.ucla.edu or or ccle. Midterm and Final Exams will include material discussed in the book, lecture, and possibly articles. The Midterm and FINAL exams are NOT BASED ON GROUP WORK and each student need to turn in their own paper. Academic Honesty Policy Summary: As a student and member of the University community, you are here to get an education and are, therefore, expected to demonstrate integrity in your academic endeavors. All students must uphold University of California Standards of Student Conduct as administered by the Office of the Dean of Students. Students are subject to disciplinary action for several types of misconduct, including but not limited to: cheating, multiple submissions, plagiarism, prohibited collaboration, facilitating academic dishonesty, or knowingly furnishing false information. You may have assignments or projects in which you work with a partner or with a group. For example, you are welcome, and even encouraged, to work with others to solve homework problems. Even though you are working together, the assignment you submit for a grade must be IN YOUR OWN WORDS, unless you receive specific instructions to the contrary. For more information about academic integrity, please go to www.deanofstudents.ucla.edu NOTICE: If you have a disability which will make it difficult for you to carry out the work for this course or if you anticipate a need for special assistance or accommodation due to a disability, please contact the Office of Services for Students with Disabilities as soon as possible. Efforts will be made to arrange appropriate and/or suitable accommodation.

“What Can I Do to Pass This Class?” Is a Question that should be asked at the Beginning of the Quarter Not at the End. "Give me some extra work to do in order for me to pass" sounds preposterous after we are done with all the work for the quarter and not fair to other students. "Do all the credits first before you ask for extra credits" Welcome and Good Luck! 4...
