The wide availability of statistical software has made it much easier for students to undertake their own statistical analysis, but this has come with a downside. The analysis of genetic studies has formed its own discipline called bioinformatics, which is somewhat different. Biostatistics focusses on areas such as design and analysis of clinical trials, the analysis of rates of disease, measures of the association between exposures and outcome, survival analysis, diagnostic testing, disease clustering and surveillance, disease screening, reliability and method comparison studies and biological assays. Whilst statisticians are usually trained in Schools of Mathematics and Statistics, biostatistics is taught in Schools of Public Health and Epidemiology, however, there is much overlap. Biostatisticsīiostatistics (also called medical statistics) is the discipline of statistical theory and methods applied in the health context. It is broadly covered by the disciplines of biostatistics and epidemiology. Quantitative researchĪs its name implies, quantitative research is all about numbers. The above explanation only touches on many of the different theories used in qualitative research. Finally, grounded theory focuses on generating a theory from research data to describe what is happening in a social setting. This is an approach developed by anthropologists to learn about cultures, and is now used to study behaviour and social interactions. A second major method of analysing qualitative data is by using ethnography.

There are at least three schools of thought on how to undertake a phenomenological analysis. Phenomenology or analysing the lived experience is another method of analysis. Quite often, a simple thematic analysis is suitable, as long as it is undertaken in a systematic and reproducible fashion. There are many different ways of analysing data obtained from qualitative research. The sample size is typically small, and respondents deliberately selected because of their characteristics.
Some common methods of collecting qualitative data include focus groups (group discussions), individual interviews, and participation/observations.

For example, a clinical trial might show that an intervention is not effective, and additional qualitative research might help explain why it did not work. Qualitative research can also be used as an adjunct to quantitative research. For example, qualitative research is often used to help develop a questionnaire. Qualitative research can be either a study in its own right, usually undertaken when little is known about a topic, or as an aid to undertaking quantitative research. Qualitative Research is primarily exploratory research, used to gain an understanding of underlying reasons, opinions, and motivations. The data themselves are usually words or observations, unlike quantitative research, where the data are numbers. In the qualitative approach the type of data to be acquired focuses on experiences, thought, feelings and behaviours. Because the proposed study contains both qualitative and quantitative components, it could be best described as a mixed methods PhD. The methods for Aims 2 and 4 can be described as qualitative research, whereas the methods for Aims 3 and 5 are described quantitative research.
In Table 2, the method for Aim 1 was a literature review, which we have already discussed.
