Statistical analysis

Primary and secondary outputs, hypotheses, and statistical methods should be specified and justified in a protocol before beginning the experiments. Sample sizes, in terms of hives per area for climatologically different regions (when relevant), should be large enough to provide sufficient statistical power. Whenever possible, results of the analyses should be accompanied by confidence intervals. Refer to the BEEBOOK paper on statistics (Pirk et al., 2013) and to the CVMP guideline on Statistical Principles for Veterinary Clinical Trials (EMEA/CVMP/816/00).
