In a post earlier this month, I discussed a new Journal of Neuroscience paper on statistical power in neuroscience. That paper was a response to and reanalysis of a previous article, and in my post I noted my surprise that the new paper hadn’t appeared in Nature Reviews: Neuroscience (NRN), where the original paper had been published. It turns out there’s a bit of a backstory here. According to the senior author of the new paper, Jon Roiser, his group did want to submit to NRN, but ...read more

Posted on Categories Discover MagazineLeave a comment on Are Underpowered Studies Ever Justified?

Is a small scientific study better than none at all? A provocative piece in Frontiers in Psychology raises the question of whether we should ever do under-powered studies.
