# STATS 240 : Design and Structured Data

## Science

### Course Prescription

An introduction to research study design and the analysis of structured data. Blocking, randomisation, and replication in designed experiments. Clusters, stratification, and weighting in samples. Other examples of structured data.

### Course Overview

STATS 240 covers two of the most important types of statistical research studies: surveys and designed experiments. STATS 240 is recommended for anyone doing a major in Statistics but is also useful for undergraduate students from other majors in Science, Engineering, and Commerce, who are interested in sample surveys or designed experiments. The characteristics of a well-designed survey, as well as practical considerations and administrative issues, are discussed. Different sampling methods (stratified, cluster, multistage) are introduced and their strengths and weaknesses are explored. The proper analysis of data from surveys based on the sampling design and making valid inferences about a population using this analysis is emphasized. The underlying fundamental principles (replication, randomisation and blocking) of statistical experimental design are explained and their importance is discussed. The concepts of block structure and treatment structure of an experiment are introduced. The characteristics and proper analysis (using the appropriate data model) of the most common types of designs (completely randomised, random complete block, balanced incomplete block, split-plot) are explored in detail with an emphasis on making valid inferences about the system being studied.

This course is a standard 15-point course and students are expected to spend 12.5 hours per week involved in each 15-point course that they are enrolled in.

For this course, a typical weekly workload includes:

• 3 hours of lectures
• 5-6 hours of work on assignments, quizzes, and/or test preparation

### Delivery Mode

#### Campus Experience

Attendance is expected at scheduled activities including labs to complete components of the course.
Lectures will be available as recordings. Other learning activities including labs will not be available as recordings.
The course will not include live online events.
The activities for the course are scheduled as a standard weekly timetable.
Attendance in person will be required for any on campus test and exam.

### Learning Resources

Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).

Please remember that the recording of any class on a personal device requires the permission of the instructor.

Lecture Notes:

• Lecture notes are provided on Canvas

### Student Feedback

During the course Class Representatives in each class can take feedback to the staff responsible for the course and staff-student consultative committees.

At the end of the course students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback.

Your feedback helps to improve the course and its delivery for all students.

Students found that the regular online quizzes aided their learning and these will continue in 2024. The Statistics Assistance Hub will provide tutor support for quizzes and assignments.

The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the internet. A student's assessed work may be reviewed for potential plagiarism or other forms of academic misconduct, using computerised detection mechanisms.
