Power failure: why small sample size undermines the reliability of neuroscience

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.

This is an interesting read which shows that research suffers from a low number of people taking part in studies. This in turn affects the statistical validity of the research. That’s not to say the research is invalid, it is just worth understanding more about the efficacy of the research, especially as L&D starts to embrace neuroscience with open arms.
