# Statistics for Scientists Introduction

1 Day Course

This one day introductory course to the fundamental of statistics, relevant to all professionals in the analytical sciences, life sciences and related fields.

• We limit numbers to 20 per course so that each delegate gets the opportunity to ask questions and fully participate in tutorial exercises
• When delivered on-site we can design the course material to suit your specific training needs
• Customisable written assessments are available if required

This course comprehensively covers the basic concepts and methods of statistics with applications in the field of analytical sciences. During this course, we will demonstrate methods of exploring, organising, and presenting data, and introduces the fundamentals of probability.
We will:
- explore the foundations of statistical inference, including the concepts of parameters and estimates
- explore the use of the statistical measures, confidence intervals, and hypothesis tests.

Who is this course for

The aim of the course is to foster an interest in applied statistics and equip scientists and project managers to confidently apply statistical techniques to investigate and improve data quality.

Previous knowledge

Good knowledge of chromatography and statistical analysis is advantageous.
