In this series of ‘eat your greens‘ posts looking at core statistical concepts in more detail, we have looked closely at what a test of statistical significance actually is. In particular, we have focused on how to interpret the statistical probability value that various tests generate. This value, often labelled ‘P=’, ‘Prob’ or ‘Sig.’ in …
IBM have released a new update to SPSS v27. Interestingly, this is a ‘dot’ release that contains a number of useful functional improvements rather than the usual bug fixes or third-party compatibility enhancements. The new procedures include three additional statistical tests for comparing differences in proportions. These procedures were introduced as syntax only commands in …
In these videos Jarlath Quinn introduces the concept of Structural Equation Modelling with SPSS AMOS. In the first video Jarlath uses the example of creating a simple linear model to illustrate the functionality in the AMOS interface. In the second video, Jarlath shows how to perform a basic Confirmatory Factor Analysis in AMOS. Watch the …

Earlier in this series of ‘eat your greens‘ postings I looked at the issue of declaring something to be ‘statistically significant’. The purpose of that post was to highlight the fact that not all statistical results are worthy of being regarded as ‘eureka!’ moments just because the findings are unlikely to have occurred due to …
