This one-day workshop gives you the opportunity to consider issues that we are sure you worry about from time to time in your everyday analysis of consumer and sensory test data. Our key tool is Analysis of Variance but this technique makes assumptions about the underlying distributions in our data – what are these assumptions and do they matter? We will cover repeated measures analysis, when and how it should be used and look at simple nested models.. 
We will also discuss the over reliance on statistical significance in reporting data, the relevance (or not) of multiple comparison tests and alternative approaches using randomisation tests.

The day will be carried out using the ANOVA functionality in XLSTAT


Anne Hasted began her career as an academic statistician at Reading University, leaving in 1989 to set up Qi Statistics Ltd offering statistical training and consultancy support to research and industry. She has wide training and consultancy experience in the food industry, particularly in the area of product improvement.



Quick review of the basics. Properties and precision of means – standard error- confidence intervals. Central Limit theorem – its relevance to us.  Statistical significance –what does it tell you – what does it not tell you. Dangers and alternatives.


ANOVA Exercise as refresher


Analysis of Variance options and outputs examined: Model parameterisation. Unbalanced test data, the different sums of squares, which to use, LSMEANS – how to interpret them 


The four assumptions we make in the analysis.
Normality, Homogeneity, Independence, No Outliers. How to check them
How “bad” can my data be before I have to worry? Which assumptions are most critical.  ANOVA using JAR or even CATA data


Multiple comparison tests, family error rate and false discovery rate. How to deal with all the options available.


Fitting Mixed Models to replicated test data– classical ANOVA approach v  REML. Which residuals to examine for replicated tests (benefit of central limit theorem)




Mixed Models Continued


Repeated Measures ANOVA –when should it be used? traditional approach of significance adjustment v modern approach of modelling error structure


Fitting Nested models -their application in investigating demographic effects


Modelling products and variables (covariance) – satiation trial data
