艺术学科研究生文凭课程（PGDipArts）需要两个学期的全日制课程，或与之相当的兼读制课程。它需要一个结构化的研究生课程计划，并且在某些情况下，需要一项监督研究，其中包括一份或两篇必需的论文。正常的入学要求是所提议课程的主要主题的完整的文学学士学位。统计学作为一个研究领域，涉及数字数据的收集，分析和解释。主要重点在于随机变化在所做观察中的作用，这就是为什么统计理论建立在概率概念上的原因。
Statisticians can be thought of as explorers finding information in data. They collect, analyse and interpret data to help researchers and decision-makers. The collaborative nature of statistics is one of its most rewarding features.Statisticians also design and carry out research. They rely on computational skills, quantitative abilities, analytical reasoning and communications skills.At Otago, the Statistics Group is working in ecology, bioinformatics, biostatistics, quantitative genetics and on problems such as disease spread and seismic and volcanic hazards.<br>Anywhere data are collected, analysed or interpreted, you find people with statistical training. Because the world is becoming more and more data-focused, the demand for graduates has outstripped supply. Statisticians use computational skills, statistical knowledge, quantitative abilities and communications skills to help make decisions in the face of uncertainty. Examples include evaluating the environmental effects of air, water, and soil pollutants, and designing and analysing studies to determine whether new drugs and medical procedures are safe and effective. By working in statistics, you can combine your interest with almost any other field in science, technology, or business.<br> In New Zealand, statisticians are employed in Crown Research Institutes, Government Departments such as Inland Revenue, ACC, and DOC, and companies such as Fonterra, Meridian Energy, and Spark.
