**Description**

This module will equip the student with advanced statistical techniques for analysing data in the Nutrition fields. It provides the students with the ability to apply appropriate statistical techniques to data sets gathered during project work and also to comment on and rate techniques used in existing studies.

### Learning Outcomes

*On completion of this module the learner will/should be able to;*

**1.**

Formulate conclusions by applying a range of advanced statistical techniques in the analysis of data sets.

**2.**

Model the relationships between variables using regression analysis

**3.**

Explain the concept of survival analysis and apply the most commonly used mortality/survival functions

**4.**

Justify the selection and application of appropriate quantitative analysis in nutrition related literature and reports.

**5.**

Use a statistical software package to carry out analysis on data sets.

### Teaching and Learning Strategies

The teaching methods used will be a combination of online lectures, self study, on line tutorials, problem solving exercises and computer based learning

### Module Assessment Strategies

The student will be assessed by means of both summative and formative assessment. The summative assessment will consist of two practical based projects where the student will be examined on both their theoretical knowledge of data analysis and statistics and their use of statistical analysis software to apply this knowledge with the emphasis on the practical application of statistics. The student will also have to complete an online end of module exam which will be in the form of an open book quiz.

The student will also have access to online self-assessment quizzes as part of the formative assessment. These quizzes will allow the student to monitor their own progress on the module as well as identify any knowledge gaps they may have.

### Repeat Assessments

The student will be given a opportunity to do a repeat practical project covering the learning outcomes assessed in the projects detailed in the assessment strategy if they do not meet the requirements to pass the module and their project work was of a sub standard level.

The ability to analyze and interpret enormous amounts of data has become a prerequisite for success in allied healthcare and the health sciences. Now in its 11th edition, Biostatistics: A Foundation for Analysis in the Health Sciences continues to offer in-depth guidance toward biostatistical concepts, techniques, and practical applications in the modern healthcare setting. Comprehensive in scope yet detailed in coverage, this text helps students understandand appropriately useprobability distributions, sampling distributions, estimation, hypothesis testing, variance analysis, regression, correlation analysis, and other statistical tools fundamental to the science and practice of medicine. Clearly-defined pedagogical tools help students stay up-to-date on new material, and an emphasis on statistical software allows faster, more accurate calculation while putting the focus on the underlying concepts rather than the math. Students develop highly relevant skills in inferential and differential statistical techniques, equipping them with the ability to organize, summarize, and interpret large bodies of data. Suitable for both graduate and advanced undergraduate coursework, this text retains the rigor required for use as a professional reference.

*Statistics in Food Science and Nutrition*Springer Science & Business Media

ISBN 9781461450092 ISBN-13 1461450098

Many statistical innovations are linked to applications in food science. For example, the student t-test (a statistical method) was developed to monitor the quality of stout at the Guinness Brewery and multivariate statistical methods are applied widely in the spectroscopic analysis of foods. Nevertheless, statistical methods are most often associated with engineering, mathematics, and the medical sciences, and are rarely thought to be driven by food science. Consequently, there is a dearth of statistical methods aimed specifically at food science, forcing researchers to utilize methods intended for other disciplines. The objective of this Brief will be to highlight the most needed and relevant statistical methods in food science and thus eliminate the need to learn about these methods from other fields. All methods and their applications will be illustrated with examples from research literature.

*Statistics for Sports and Exercise Science*Prentice Hall

ISBN 0132042541 ISBN-13 9780132042543

Statistics in Sport and Exercise Science assumes no prior knowledge of statistics and uses real-life case studies to introduce the importance of statistics in sport and exercise science. Statistical tests and techniques are described here in a friendly and easy-to-understand manner, giving you the confidence to analyses data and complete your own statistical studies. This is the best statistics text I have come across in 7 years of teaching on undergraduate sport degrees. Students have always struggled to see the application of statistics to their degree Statistics for Sports and Exercise Science eliminates this problem, - Dr Mick Wilkinson, Department of Sport Sciences, Northumbria University "Easily the best book in the area, specific material for sport students."- Dr Rodney Kennedy, School of Sport Studies, University of Ulster "I really like the Newell book and will definitely be recommending it to the students on my two research methods modules... The information in the book is first class." - Dr Adrian W Midgley, Department of Sport, Health and Exercise Science, University of Hull Incredibly easy to read, full of real-life examples, and very much appropriate for Sports Science students. - Dr Kate Reed, Department of Biological Sciences, University of Essex
