Introduction to DOE – Bundle

Discover data visualisation tools, learn the principle underlying hypothesis testing and sample size calculations. Harness the power of design of Experiments “DOE” techniques to control variation and maximise data information.

This module is aimed at all scientific staff who wish to design and implement efficient studies and experiments and who must make decisions based on the data collected. This module introduces key concepts in statistics and data analysis. It assumes that participants either have no previous knowledge of statistics or that they have not used statistics for a long time.
Upon completion of this module, participants will be able to:
    • Understand the difference between descriptive & inferential statistics
    • Appreciate the value of exploratory methods in preliminary data analysis & design of experiments
    • Explore, characterise and identify problems and trends in data using plots
    • Use descriptive statistics to summarise data
    • Understand the concepts of hypothesis testing: risks, p-value, confidence intervals, power
    • Identify the appropriate statistical test based on the study objective
    • Understand the importance of sample size calculations and the required input parameters
    • Understand the importance of statistical design of experiments and benefits in R&D
    • Learn the experimental designs most widely used in practice
    • Choose an appropriate experimental design based on the study objectives
    • Construct and implement the design selected
    • Analyse the data collected based on the design used and its underlying assumptions
