The Department of Statistics at Macquarie University is the largest statistics department at an Australian university. It is a widely respected and a pivotal faculty across several disciplines for degrees in Bachelor of Arts, Bachelor of Science, Bachelor of Economics and Bachelor of Commerce.

Commercially and in research the department applies statistics to a myriad of fields, including medicine, social science, biology, sport and finance. As a leader in the field, the Statistics Department uses and develops pioneering software for data analysis, presentation, and web-database engineering.

As befits its size, the department offers the full range of statistical activity, from training undergraduates to supervising postdoctoral scholars.

At the undergraduate level, statistics units are sometimes a compulsory component of an undergraduate degree. Statistics can also be a major area of study in itself with programs of study including Statistics, Information Science, Statistics and Computing, Operations Research, and Statistics and Econometrics.

At the postgraduate level, the department delivers the Master of Philosophy and the PhD in Statistics, while statistics is a structural necessity for completion of the Master of Philosophy and the Doctor of Philosophy in several disciplines.
