Experimental Design: the Good, the Bad and the Ugly
Wednesday, 26 June 2019, 9am to 5pmApply for this course
This course is scheduled each term.
This course addresses some of the fundamental issues that are behind designing good experiments (focusing on pre-clinical experiments exclusively), the bedrock of reproducible science.
The course will deal with those concepts, their links with statistical analyses generally and some of the traps that we have all fallen into. We will also address statistical issues relevant to animal research depending on the composition of the audience, in a session where the words 'enjoyment' and 'statistics' can hopefully share the same sentence.
A series of interactive lectures and scenarios delivered by Manuel Berdoy, BMS, Oxford.
At the end of the course, attendees should be able to:
- Describe some of the factors affecting reproducibility and external validity.
- List the different types of formal experimental designs (e.g. completely randomised, randomised block, repeated measures, Latin square and factorial experimental designs).
- Explain the concept of variability, its causes and methods of reducing it
- Describe possible causes of bias and ways of alleviating it
- Identify the experimental unit and recognise issues of non-independence (pseudo-replication).
- Describe the six factors affecting significance, including the meaning of statistical power and 'p-values'.
- Identify formal ways of determining sample size.
- Explain the fundamental principles behind the output of an ANOVA, including “blocking” and “interactions”.
