This Program aims to provide engineers and technologists with the understanding and practical capabilities needed to convert data into information, and then to represent this information in ways that it can be readily exploited.

• To provide delegates with a working vocabulary of analytical terms to enable them to converse with people who are experts in the areas of data analysis, statistics and probability, and to be able to read and comprehend common textbooks and journal articles in this field.
• To provide delegates with both an understanding and practical experience of a range of the more common analytical techniques and data representation methods, which have direct relevance to a wide range of analytical problems.
• To give delegates the ability to recognize which types of analysis are best suited to particular types of problems.
• To give delegates sufficient background and theoretical knowledge to be able to judge when an applied technique will likely lead to incorrect conclusions.
• To provide delegates with an overview of the main data analysis applications within engineering systems.

The course has been designed for engineers, technologists, and professionals whose jobs involve the manipulation, representation, and analysis of data. Basic familiarity with PC's and in particular with Microsoft. Excel. is assumed. Aside from this, no other software familiarity or previous data analysis experience is required.

The course adopts an applications-oriented approach, minimizing the time spent on the mathematics of analysis and maximizing the time spent on the use of practical methods. Most of the time, delegates will work on computers, using spreadsheets and the specialized analytical software MATLAB to investigate real data from a wide range of example applications. Delegates are encouraged to bring their own data with them on CD, and time will be set aside to address delegates' individual issues and concerns.
