Complex Assertions for Dynamic Data: Assertion tests often struggle with verifying dynamically generated data due to variability...
This may be down to our brain's 'mirror neurons', which are known to mimic others' actions. The hypothesis will need to be thoroughly tested, however. It might even be the case that we could use neuroaesthetic studies to understand the longevity of some pieces of artwork. While the ...
In general, the two-stage approach to modeling (i.e., test for assumptions, and fit standard model if non-significant or robust model if significant) is not recommended (see this excellent CV thread: A principled method for choosing between t test or non-parametric e.g. Wilcoxon in small...
Is there enough information or data to support the given hypotheses? Identify assumptions: are you sure the sources you found are unbiased? Are you sure you weren’t biased in your search for answers? Establish significance: what piece of information is most important? Is the sample size ...
