Data Analysis 2

This subject has the following teaching availabilities in 2009:

One of

• 620-152 (prior to 2008)
• Data Analysis 1
• 620-160 (prior to 2008)
• Experimental Design and Data Analysis
• 316-130 Quantitative Methods 1.

Students may only gain credit for one of Data Analysis 2, 620-270 (prior to 2009), Applied Statistics for Optometrists, Statistics for Mechanical Engineers.

Passing Data Analysis 2 precludes subsequent credit for Data Analysis 1 or Experimental Design and Data Analysis.

This subject demonstrates the importance of statistical methods for interpreting data, the role of exploratory and formal data analysis and the importance of experimental design. Students should learn to examine data to determine underlying structures, formulate statistical models for a range of practical situations and check the assumptions of the model in specific situations. They should also learn to use the computer to carry out standard statistical analyses and to express conclusions in scientifically useful terms.

Statistical inference topics include: estimation; confidence intervals; hypothesis testing. Correlation and regression, including residuals, diagnostics, transformations. Multiple linear regression, including collinearity; model selection; and polynomial regression. Analysis of variance topics include: one-way and two-way models, including interaction and its interpretation. Design of experiments topics include: randomisation; replication; blocking; standard designs including completely randomised, randomised block and Latin square designs; factorial experiments: analysis; blocking and confounding. Analysis of covariance. Logistic regression for categorical data.

Students completing this subject should:

Comprehend:

• how statistical models are used to analyse data;
• the basic principles of experimental design.

Have developed skills:

• to examine the data to determine underlying structures;
• to formulate statistical models for a range of practical situations;
• to check the assumptions of a model in specific situations;
• to use the computer to carry out standard statistical analyses;
• to express the results of a statistical analysis in scientifically useful terms.

Appreciate:

• the importance of statistical methods for interpreting data;
• the role and interplay of exploratory and formal aspects of data analysis;
• the importance of experimental design;
• the application of statistical software.

Up to 50 pages of written assignments 25% (due during semester); a 3-hour written examination 75% (held in the examination period).

This subject potentially can be taken as a breadth subject component for the following courses:

• Bachelor of Arts
• Bachelor of Commerce
• Bachelor of Environments
• Bachelor of Music

You should visit learn more about breadth subjects and read the breadth requirements for your degree, and should discuss your choice with your student adviser, before deciding on your subjects.

In addition to learning specific skills that will assist students in their future careers in science, they will have the opportunity to develop generic skills that will assist them in any future career path. These include

• problem-solving skills: the ability to engage with unfamiliar problems and identify relevant solution strategies;
• analytical skills: the ability to construct and express logical arguments and to work in abstract or general terms to increase the clarity and efficiency of analysis;
• collaborative skills: the ability to work in a team;
• time management skills: the ability to meet regular deadlines while balancing competing commitments;
• computer skills: the ability to use an appropriate computing package.

Students undertaking this subject will be required to regularly access an internet based computer and to use MINITAB for statistical analysis.

Students undertaking this subject will be expected to be competent in the use of MINITAB statistical software.
