Biostatistics in the Faculty of Medical and Health Sciences

FMHS has biostatisticians with whom you can discuss your research problems at the design, analysis or interpretation phase. With expertise in research methods and health sciences, the biostatistics consulting team supports researchers across the faulty with the highest quality biostatistical advice and research collaboration.

This service is open to all staff and graduate students in the faculty to provide advice and assistance with:

  • The design of research projects, including the preparation of grant proposals
  • Choice and application of statistical methods
  • Data visualization and presentation
  • reporting and interpretation of results
  • Conducting of more complex analyses can also be provided in some cases

The biostatisticians are experienced primarily with the SAS, R and Stata statistical analysis systems, but can work with researchers using other statistical packages. Please note that statistical consulting is for study design and data analysis advice, not software tutorials. Researchers are expected to perform their own data preparation, descriptive statistics and basic analysis, with biostatistician’s guidance if required.

There is limited consultation time available free of charge, and in general it is not possible to provide more than 4 hours consultation time per project per year. If further biostatistical support is needed, this will be assessed on an individual basis. Funded projects should include funding for statistical services in the budget, and various options for doing this can be discussed. Extensive hands-on data analysis is not generally available without funding.

The four FMHS biostatisticians work with researchers from across the faculty. They are based on the Tāmaki Campus but also run an office on the Grafton Campus on Wednesdays.

Support for graduate research students

Prior to students starting on research projects, the statistical support needed for the project should be evaluated by the Faculty in conjunction with biostatisticians.

We can offer up to 4 hours per project per year for graduate research students, including advice on study design, analysis and/or interpretation of results. If further ongoing biostatistical support is required, a biostatistician should be involved as a co-supervisor or advisor. If you are a research student seeking a biostatistical supervisor for your research project, please make this clear when you submit your request form (available in the contact section).

Please note that research students should perform their own data preparation and descriptive statistics. As a requirement of gaining their qualification, students are usually expected to learn to conduct the analysis themselves, with biostatistician’s guidance if required.

Collaboration and authorship

We follow the authorship guidelines as published by the International Committee of Medical Journal Editors (ICMJE). If a statistician made significant contribution to a research project or the development of a manuscript and met the authorship criteria of ICMJE, the statistician should be included as an author on publications resulting from the work.

The appropriateness of authorship should be discussed and agreed upon with the biostatistician in the initial meeting. This may be subject to renegotiation if the role changes substantially.

For more information, see the ICMJE website.

Researchers are strongly encouraged to discuss their project with us at the earliest stage possible, in order to ensure high quality statistical design and analysis. Please include details about any deadlines you are working to. Due to limited capacity, we may not be able to prioritise last-minute requests.

Once the request is submitted, you will be contacted within 5 working days. Sometimes a phone conversation and/or email will be sufficient, or we can organise an initial face-to-face meeting at either Tāmaki or Grafton Campuses.
