Abstract
The lack of reproducibility in biomedical research has been consistently attributed to the misuse of statistics, naïve inference/extrapolation from animal models, and fraud. However, optimization of statistical analysis and caution in interpreting experimental outcomes cannot overcome flaws in experimental design and execution. These include: the absence of a credible hypothesis for running an experiment; clearly defining outcomes before the experiment is run; the use of appropriate controls, randomization of subjects; the validation/authentication of all reagents (compounds, cell lines, animals, antibodies) and equipment; the collection, preservation, and annotation of raw data; and steps to contain or eliminate investigator bias. Collectively these measures will avoid a GIGO (garbage in, garbage out) paradigm that no amount of postexperimental tinkering, including P-hacking, can objectively and legitimately correct. The present chapter addresses measures to facilitate best practices in experimental design and execution that will aid in improving reproducibility.
