**Description**

This course introduces the student to advanced statistical techniques for analysing data in the Public Health and Health Promotion 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.**

Demonstrate the application of advanced statistical techniques in the analysis of population health data.

**2.**

Describe the selection and application of appropriate quantitative analysis in global health literature and reports.

**3.**

Identify key features of quantitative analysis including descriptive and inferential statistics in a range of study designs.

**4.**

Evaluate the appropriateness of statistical approaches in a range of public health and health promotion settings.

**5.**

Perform statistical analysis on health data using appropriate software for statistical analysis.

### Teaching and Learning Strategies

The teaching methods used will be a combination of lectures, self-study, labs, tutorials, and any combination of discussion, case study, problem-solving exercises and computer-based learning.

### Module Assessment Strategies

This module will be assessed on both a theoretical and practical level.

There will be three summative assessments:

**Assessment 1**

This will be a classroom based assessment where the student will be assessed on their ability to use death rates and measures of morbidity and fertility to analyse the health of a population.

**Assessment 2**

There will be an assessment run jointly with Epidemiology on the critical appraisal of statistics used in a research study (research paper). In the part of the assessment relevant to this module, the student will be expected to identify the statistical methods used, the key results and the appropriateness of the statistical methods.

**Assessment 3**

Assessment 3 will be a practical assessment using a statistical software package to carry out advanced statistical analysis on a dataset.

The students will also be assessed formatively during class and laboratory practicals with feedback given to enable them to perform effectively in the summative assessments.

### Repeat Assessments

Where the student fails to achieve the pass mark in the module, they may be asked to repeat the final exam or complete a practical assignment or a combination of both.

*Biostatistics: An Applied Introduction for the Public Health Practitioner*Cengage Learning

ISBN 9781111035143 ISBN-13 1111035148

BIOSTATISTICS: AN APPLIED INTRODUCTION FOR THE PUBLIC HEALTH PRACTITIONER is designed to help public health researchers, practitioners, and students understand and apply essential biostatistics concepts. This innovative new text emphasizes real-world public health problems and the research questions they inspire. This text provides a unique introduction to statistical concepts and methods used by working professionals during investigations. Unlike other texts that assume a strong knowledge of mathematics or rely heavily on formulas, BIOSTATISTICS consistently emphasizes the public health context, making even complex material both accessible and relevant. The first chapter introduces common statistical terminology by explaining them in clear language, while subsequent chapters explore the most useful and versatile statistical methods for a variety of public health research questions. For each type of question, the author presents a range of applicable methods, from descriptions of data to simple statistical tests, generalized linear models, and multiple variable regression. The text's step-by-step coverage of fundamental concepts is perfect for students new to the field, but its depth and detail also make it ideal for two-course series in M.P.H. or M.H.A. programs, or for working professionals. Readers at all stages of their professional lives can draw on this invaluable resource to help them interpret and conduct statistical studies and support effective evidence-based practice.

*SPSS Survival Manual*

ISBN 033526154X ISBN-13 9780335261543

The SPSS Survival Manual throws a lifeline to students and researchers grappling with this powerful data analysis software. In her bestselling guide, Julie Pallant guides you through the entire research process, helping you choose the right data analysis technique for your project. From the formulation of research questions, to the design of the study and analysis of data, to reporting the results, Julie discusses basic and advanced statistical techniques. She outlines each technique clearly, with step-by-step procedures for performing the analysis, a detailed guide to interpreting data output and an example of how to present the results in a report. For both beginners and experienced users in psychology, sociology, health sciences, medicine, education, business and related disciplines, the SPSS Survival Manual is an essential text. Illustrated with screen grabs, examples of output and tips, it is supported by a website with sample data and guidelines on report writing. This sixth edition is fully revised and updated to accommodate changes to IBM SPSS procedures, screens and output. It covers new SPSS tools for generating graphs and non-parametric statistics, importing data, and calculating dates. 5 star Amazon review: "This is the book I wish I had whilst studying SPSS and experimental design on my MSc in social research methods. It is the clearest guide to SPSS that I have come across and it is very practical and easy to use. It has allowed me to revise statistical methods in a matter of days and I have gained a better understanding of these techniques than I had through using other much lengthier texts."

*Biostatistics*Wiley

ISBN 1118302796 ISBN-13 9781118302798

This 10th edition of Biostatistics: A Foundation for Analysis in the Health Sciences, 10th Edition should appeal to the same audience for which the first nine editions were written: advanced undergraduate students, beginning graduate students, and health professionals in need of a reference book on statistical methodology. Like its predecessors, this edition requires few mathematical prerequisites. Only reasonable proficiency in algebra is required for an understanding of the concepts and methods underlying the calculations. The emphasis continues to be on an intuitive understanding of principles rather than an understanding based on mathematical sophistication. For most of the statistical techniques covered in this edition, we discuss the capabilities of one or more software packages (MINITAB, SAS, SPSS, and NCSS) that may be used to perform the calculations needed for their application. Resulting screen displays are also shown.

*Quantitative Methods for Health Research*John Wiley & Sons

ISBN 9780470022740 ISBN-13 0470022744

Quantitative Research Methods for Health Professionals: A Practical Interactive Course is a superb introduction to epidemiology, biostatistics, and research methodology for the whole health care community. Drawing examples from a wide range of health research, this practical handbook covers important contemporary health research methods such as survival analysis, Cox regression, and meta-analysis, the understanding of which go beyond introductory concepts. The book includes self-assessment exercises throughout to help students explore and reflect on their understanding and a clear distinction is made between a) knowledge and concepts that all students should ensure they understand and b) those that can be pursued by students who wish to do so. The authors incorporate a program of practical exercises in SPSS using a prepared data set that helps to consolidate the theory and develop skills and confidence in data handling, analysis and interpretation.
