Description
This subject gives an introduction to probability theory and statistics. Students learn how to describe random phenomena using the language of probability, and how this is applied in a statistical framework to solve real world problems. The first half of the subject introduces the students to important concepts in probability, such as random variables and their probability distributions. Fundamental properties such as expectations, independence and the Central Limit Theorem are discussed. The second half of the course introduces classical statistical inference and its connection to probability theory. Sampling distributions and their use in constructing confidence intervals and hypothesis testing are discussed. The course ends by introducing simple linear regression and analysis of variance techniques.
Subject learning objectives (SLOs)
Upon successful completion of this subject students should be able to:
1.  understand how to use descriptive statistics to properly summarize a dataset; 

2.  understand basic properties of random variables and their probability distributions; 
3.  determine an appropriate statistical model for a given dataset and conduct sensible statistical inference; 
4.  formulate a linear regression model and carry out appropriate statistical inference. Understand the limitations of the linear regression model and the implications of model misspecification; 
5.  analyse realworld datasets using modern statistical software. Apply theoretical knowledge from the lectures and tutorials to solve realworld problems; 
Contribution to the development of graduate attributes
This subject teaches students basic concepts in probability theory and their application in statistical modelling and inference. Students learn how to formulate an appropriate statistical model for a given dataset and how to carry out sensible statistical inference. The subject also trains the students in using modern statistical software to solve realworld problems and how to effectively communicate these solutions. Thus this subject is contributing to the following graduate attributes:
Graduate Attribute 1  Disciplinary knowledge.
The lectures develop the theoretical understanding of the material. The tutorials allow the students to apply the theory to solve exercises and deepen their understanding of the material.
Graduate Attribute 2  Research, inquiry and critical thinking.
The lectures present approaches to formulate statistical models of various types of data. The students will develop skills in determining the correct approach themselves in the tutorial classes.
Graduate Attribute 3  Professional, ethical and social responsibility.
The tutorial classes encourage the students to work in groups under the supervision of a tutor. The computer lab is done in small groups and trains the students' ability to work effectively and responsibly.
Graduate Attribute 4  Reflection, innovation, creativity.
The lectures teach the students to develop a creative mindset to solve a statistical problem. The tutorials give the students the opportunity to train their ability to design creative solutions to statistical problems. The computer labs train the students ability to critically evaluate statistical procedures and interpretation of results.
Graduate Attribute 5  Communication.
Presentation of solutions to problems using appropriate professional language is emphasised in the computer labs.
Teaching and learning strategies
The subject consist of a combination of complementary inclass and selfstudy activities. Before class meetings, students are expected to engage with background material that will introduce the fundamental concepts covered in the subject. The facetoface classes (one 90 minutes + one 60 minutes of weekly lectures, one 120 minutes weekly tutorial, and two 180 minutes computer labs) will incorporate a range of teaching and learning strategies, including individual and collaborative group work, presentation of worked examples and applying modern statistical software to analyse realworld datasets. Students are to review the relevant material made available on UTSOnline prior to classes.
Content (topics)
