Elective

2

After completing this unit, students will be able to:

• identify an appropriate statistical method for testing associations with a categorical and a continuous outcome;
• conduct descriptive and univariable regression analyses using standard statistical software;
• build multivariable linear and logistic models for measurg association of a variable with an outcome after accounting for other variables and confounders;
• interpret the output of regression analyses from standard statistical software and present the results in research papers and project reports;
• evaluate statistical results presented in epidemiology journals (such as Preventive Veterinary Medicine); and
• identify clustering in epidemiological data and have basic skills to account for clustering while analysing hierarchical data.

  Assumed Knowlege

   

  This unit involves students having a basic understanding of the statistical principles and data analysis similar to the level of Introductory Biostatistics (PUBH5018) offered by the School of Public Health, The University of Sydney. In particular, the students must have knowledge of the following topics:

  • variables and their types;
  • calculation and interpretation of the summary statistics(measures of central tendency and dispersion);
  • descriptive analysis of data including preparation of scatter plots, bar charts, box-and-whisker plots and histograms;
  • inferential statistics, null and alternate hypothesis, p-values, one and two tailed tests, level of significance, Type-I and Type-II error, and confidence intervals;
  • z- and t-tests to compare of difference of means and chi-square test to compare difference in proportions, between two groups.
    This unit also requires understanding of fundamental epidemiological principles covered in Veterinary Epidemiology I (VETS 7004), such as:
    • epidemiological observational studies; causal web models; and
    • measures of association, particularly odds ratios.
