# Getting to Grips With Basic Data Analysis Using XLSTAT, Reading, UK, 11th-12th September 2018

This course covers the easy to use features in EXCEL & XLSTAT for investigating, visualising and performing basic statistical analyses on data sets typical to business, research and industry settings.

#### Getting to Grips With Basic Data Analysis Using XLSTAT

You will learn how to understand your data better through simple data visualisations and how to test simple hypotheses to help inform business decisions using data. Mathematical details are kept to a necessary minimum and we focus on the interpretation of the outputs from XLSTAT and illustrate applications with case studies using data from surveys, instrumental analysis, manufacturing processes, clinical trials and biological data. There is plenty of opportunity for practice using XLSTAT through "hands on exercises" for which annotated solutions are provided.
