Power failure: why small sample size undermines the reliability of neuroscience
Clinical Trials Thursday, May 2nd, 2013Nature Reviews Neuroscience: April 10, 2013
A study with low statistical power has a reduced chance of detecting a true effect, but it is less well appreciated that low power also reduces the likelihood that a statistically significant result reflects a true effect. Here, we show that the average statistical power of studies in the neurosciences is very low. Read more
