To address the question of whether experimental seahorses preferred larger partners, the null hypothesis of no preference (i.e., B = 0.5), was tested with one-sample t tests.
Historical experience with model systems shows that the choice of the interaction investigated is crucial, since our depth of understanding will be limited by the amenability of the partners in question to experimental analyses.
The paper discusses questions of its experimental determination as well as of its application to components.
We have shown that by integrating data from different sources and through the combined analysis of data, we are able to obtain insights into the biological system under investigation that go beyond the specific research questions of each experimental design.
Some EBPH researchers have questioned the prioritization of experimental evidence, noting that study quality may be more important than whether the study is experimental or observational (Petticrew and Roberts 2003; Rychetnik et al. 2002).
The question of how these experimental results are to be explained kindled a lively debate on the nature of imagery and imagination.
One is sometimes faced with the question of whether the experimental apparatus satisfies the conditions required by theory, or conversely, whether the appropriate theory is being compared to the experimental result.
"The report released today does not answer the question of why the experimental drug protocol did not work as promised," Baich said.
Thus, before concluding that bees are not capable of solving a certain visual discrimination, researchers should address the critical question of whether their experimental designs are able to push the cognitive capacities of bees to their limits.
