# Statistic Fundamentals for Research & Industry Using Statistical Software

Product code: MAN4-4

Duration: 2 days

Pre-requisite
No previous knowledge of statistics or of the software package is necessary with this course, as we start right from the beginning. It also serves as a useful refresher course to those who once studied statistics as part of a college course.

Course Summary
This basic but wide-ranging course covers the easy to use features in statistical software for investigating, visualising and performing basic statistical techniques on data sets typical to research and industry settings. There are many basic concepts that need to be understood before statistics can be used to its full potential to give useful and informative answers. This course ensures that these concepts are understood in a non-technical way and then practiced using real data examples.

Mathematical details are kept to a necessary minimum and we focus on the interpretation of the outputs from software and illustrate applications with case studies using data from surveys, instrumental analysis, manufacturing processes, clinical trials and biological data. We aim to explain the objectives of the techniques and to send you away with a better understanding of which technique to use when.

Software
There is plenty of opportunity for practice using software through “hands on exercises” for which annotated solutions are provided.

Flexibility
We can customise the module content to meet specific requirements. We can also reduce the content to run as a 1 day course.
