Quantitative skills are among the basic and fundamental tools of professional ecologists and biologists. They are necessary to design studies, analyse data, and to assess and interpret published studies. This unit provides a solid grounding in appropriate ways to collect and analyse common types of data in biology and ecology at an intermediate level. It emphasises hands-on, practical experience with widely used statistical software and addresses the common problems often encountered in dealing with biological and ecological data. There is close integration of the lecture and practical components of the unit. The unit covers basic sampling and experimental design, data analysis using standard techniques (e.g. analysis of variance and covariance, regression, analysis of categorical data), introduces randomisation techniques, and introduces multivariate techniques for both pattern exploration and hypothesis testing. This unit is strongly recommended for ecology, biology, and environmental science students and those considering Honours. It is suitable for students commencing Masters and PhD studies who do not have a strong quantitative background.

Please check that your computer meets the minimum System Requirements if you are attending via Distance/Off-Campus.
Units are offered in attending mode unless otherwise indicated (that is attendance is required at the campus identified). A unit identified as offered by distance, that is there is no requirement for attendance, is identified with a nominal enrolment campus. A unit offered to both attending students and by distance from the same campus is identified as having both modes of study.

* The Final WW Date is the final date from which you can withdraw from the unit without academic penalty, however you will still incur a financial liability (refer to How do I withdraw from a unit? for more information).
Unit census dates currently displaying for 2023 are indicative and subject to change. Finalised census dates for 2023 will be available from the 1st October 2022. Note census date cutoff is 11.59pm AEST (AEDT during October to March).
- Understand the important features of robust experimental design;
- Understand the nuances of various kinds of biological and ecological data and the implications of particular data characteristics for analysis and interpretation;
- Have a strong working knowledge of the R and PRIMER softwares for basic statistical analyses;
- Be conversant with the application of a range of techniques used commonly in biology and ecology to analyse univariate data, such as ANOVA, ANCOVA, simple and multivariate regression, and logistic and log-linear models and other approaches to categorical data analysis;
- Be conversant with a range of techniques used commonly in biology and ecology to analyse multivariate data, including principal components analysis, cluster analysis, multidimensional scaling, CAP analyses, DISTLM, PERMANOVA and MANOVA;
- Understand the strengths and limitations of different approaches to data analysis so that you can communicate results and interpretations clearly and accurately;
- Approach data analysis and interpretation with confidence.

There is no compulsory reading for the unit.
However, students will be considerably advantaged by purchasing hard copies of the lecture manual and laboratory manual (available through UniPrint).
The recommended text is Quinn & Keough (2002), but it is not an essential requirement for the unit:
Quinn GP, Keough MK (2002) Experimental design and data analysis for biologists. Cambridge Univ. Press, UK.
Quinn & Keough is one of the most readable and accessible of texts, and it is comprehensive and up-to-date. Above all, it is specifically intended for biologists. For anyone contemplating Honours, or any other form of further study in biology or ecology, this book is strongly recommended.
There is no prescribed reading list. The following is a sample of useful texts and papers that students may find useful to refer to during or after the unit:Textbooks useful for the univariate component of the course:
Rao, P.V. (1998) Statistical Research Methods in the Life Sciences. Duxbury Press, Brooks/Cole, Pacific Grove, California.
Sokal, R.R. & Rohlf, F.J. (1995) Biometry. 3rd ed. W.H. Freeman and Company, San Francisco, CA, U.S.A.
Steel, R.G.D. & Torrie, J.H. (1980) Principles and Procedures of Statistics: a Biometrical Approach. (2nd edition), McGraw-Hill.
Quinn GP, Keough MK (2002) Experimental design and data analysis for biologists. Cambridge Univ. Press, UK. (NOTE: This is the recommended text for this unit).
Textbooks useful for the multivariate component of the course:
Clifford, H.T. and Stephenson, W. (1975). An introduction to numerical classification. Academic Press, New York.
Gauch, H.G. (1982). Multivariate analysis in community ecology. Cambridge University Press.
Green, R.H. (1979). Sampling design and statistical methods for environmental biologists. Wiley, New York.
