**Description**

This course is designed to provide an introduction to a range of statistical tools of relevance to scientists. Specific topics include an overview of statistical distributions, significance testing, uncertainty determination, linear regression and experimental design. The application of statistics for quality control and practical experience in the application of statistical features in the widely used Minitab and Microsoft Excel is particularly emphasised.

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.

### Learning Outcomes

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

**1.**

Describe basic statistical terms which are of relevance to the area of analytical science.

**2.**

Graphically display and numerically summarise data using appropriate tables, graphs and measures of centre, spread and position.

**3.**

Explain and apply concepts of basic probability including, conditional probability, Bayes' theorem, independent events and counting formulae;

**4.**

Make interferences about population parameters using sample statistics using confidence interval estimates and tests of statistical hypotheses

**5.**

Describe the application of statistics to sampling, quality control, analytical method validation and experimental design.

**6.**

Use an appropriate method for analysing relationships between variables in a dataset

### Teaching and Learning Strategies

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

The practical element of the course will be delivered separately to students in their various class groups (Biomedical Science/Medical Biotechnology, Forensic Science, Pharmaceutical Science) so that the examples used in the practical application of statistics can be tailored to their field of study.

### Module Assessment Strategies

This module will be assessed by both summative and formative means. The student will be assessed by means of both summative and formative assessment. The summative assessment will consist of continuous assessments where the student will be examined on both their theoretical knowledge of statistics and their use of statistical analysis software to apply this knowledge with the emphasis on the practical application of statistics. They will also take an end of module exam which will concentrate further on their knowledge of the application of statistics to scientific related problems and in the area of experimental design.

The formative assessment will be by means of a number of self assessment quizzes which the student can attempt in order to track their progress on the module and identify any gaps they may have or areas that they need further clarification in.

### 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 and a set of moodle quizzes or a combination of all the aforementioned.

The repeat practical laboratory assessment will be held in the first week of September prior to the autumn exam boards taking place.

Introduction to Statistics for Forensic Scientists is an essential introduction to the subject, gently guiding the reader through the key statistical techniques used to evaluate various types of forensic evidence. Assuming only a modest mathematical background, the book uses real-life examples from the forensic science literature and forensic case-work to illustrate relevant statistical concepts and methods. Opening with a brief overview of the history and use of statistics within forensic science, the text then goes on to introduce statistical techniques commonly used to examine data obtained during laboratory experiments. There is a strong emphasis on the evaluation of scientific observation as evidence and modern Bayesian approaches to interpreting forensic data for the courts. The analysis of key forms of evidence are discussed throughout with a particular focus on DNA, fibres and glass. An invaluable introduction to the statistical interpretation of forensic evidence; this book will be invaluable for all undergraduates taking courses in forensic science. Introduction to the key statistical techniques used in the evaluation of forensic evidence Includes end of chapter exercises to enhance student understanding Numerous examples taken from forensic science to put the subject into context
