STAFFING
Examiner: Shahjahan KhanModerator: Ashley Plank
REQUISITES
Pre-requisite: STA2301 or Students must be enrolled in one of the following Programs: MSBN or MSMSRATIONALE
Methods of Statistical Inference are the basis of much decision making. A basic understanding of the concepts and techniques of statistical inference is highly desirable for a practitioner of statistics.
SYNOPSIS
This course provides the students with a firm grounding in the theory and methods of statistical inference and builds on the material covered in STA2301 Distribution Theory. Parametric and non-parametric applications are covered.
OBJECTIVES
Upon successful completion of this course students should be able to:
- 1.
- determine point and interval estimators for distributional parameters and discuss the properties and distributions of those estimators; (Assign. 1, Exam)
- 2.
- understand the principles of hypothesis testing and power of a test; (Assign. 2, Exam)
- 3.
- apply the principles of hypothesis testing to a wide range of situations including parametric and non-parametric testing; (Assign. 3, Exam)
- 4.
- solve for and make inferences about the parameters of a linear model. (Assign. 3, Exam)

IMPORTANT ASSESSMENT INFORMATION
- Attendance requirements:
It is the students' responsibility to attend and participate appropriately in all activities (such as lectures, tutorials, laboratories and practical work) scheduled for them, and to study all material provided to them or required to be accessed by them to maximise their chance of meeting the objectives of the course and to be informed of course-related activities and administration. - Requirements for students to complete each assessment item satisfactorily:
To complete each of the assignments satisfactorily, students must obtain at least 50% of the marks available for each assignment. - Penalties for late submission of required work:
If students submit assignments after the due date without (prior) approval of the examiner then a penalty of 5% of the total marks gained by the student for the assignment may apply for each working day late up to ten working days at which time a mark of zero may be recorded. No assignments will be accepted after model answers have been posted. - Requirements for student to be awarded a passing grade in the course:
To be assured of receiving a passing grade a student must achieve at least 50% of the total weighted marks available for the course. - Method used to combine assessment results to attain final grade:
TThe final grades for students will be assigned on the basis of the aggregate of the weighted marks obtained for each of the summative assessment components (the examination and assignments) in the course. - Examination information:
The only materials that candidates may use in the restricted examination for this course are: writing materials (non-electronic and free from material which could give the student an unfair advantage in the examination); calculators. Students whose first language is not English may, with the Examiner's approval, take an appropriate non-electronic translation dictionary (but not technical dictionaries) into the examination. This will be subject to perusal and, if it is found to contain annotations or markings that could give the candidate an unfair advantage, it may be removed from the candidate's possession until the appropriate disciplinary action is completed. - Examination period when Deferred/Supplementary examinations will be held:
Any Deferred or Supplementary examinations for this course will be held during the examination period at the end of the semester of the next offering of this course. - University Regulations:
Students should read USQ Regulations 5.1 Definitions, 5.6. Assessment, and 5.10 Academic Misconduct for further information and to avoid actions which might contravene University Regulations. These regulations can be found at the URL http://www.usq.edu.au/corporateservices/calendar/part5.htm or in the current USQ Handbook.
