This, of course, created a paradox: to remove the alerting blue light from the bulbs, I had to expose myself to blue light from my phone, so I did it in the daytime to avoid invalidating the experiment.
If the study design implies that the control group will have to consume a product that is not part of their daily diet, this induces an interference that might invalidate the outcomes of the experiment.
Of course, modding the game this way basically invalidates the whole experiment, but it's unlikely Twitch Plays could have beaten the game otherwise.
The results from our literature review and the present experiment do not invalidate the use of microarrays for dissecting QTL.
We are conducting a grand experiment, and like any scientific experiment, you have to carefully watch how the data is being measured in the experiment environment, or problems will invalidate the measurement.
Intons-Peterson's experiment does not necessarily invalidate the claims of Kosslyn, Shepard, and others about the inherently spatial, analog nature of visual imagery.
Because including edges inferred by literature annotation could invalidate the separation of training and testing in our cross-validation experiments, we could not use all the association categories in STRING.
Notice however that this does not invalidate the model as, if we fix S≠C, we could still get a good agreement with experiments from adjusting the boundary flux parameter.
The final statement allows for a "limited and/or temporary exception" to full disclosure during the course of an experiment where such disclosure would "be likely to color the responses of the subjects and thus invalidate the research".
If some of the parameters of the two target cell model could be resolved through experiments, it would restrict the set of possible parameter values which could help validate or invalidate the two target cell model.
