Conclusion Research is built on the incredible inquisitive and resourceful minds of researchers and the urge to solve problems. Usually, studies have a power of around 80%, which means that you accept the possibility that in 20% of the cases, the real difference was missed (you concluded there was no effect when there was one). Larger samples generally yield higher statistical power. How to Calculate a Sample Size It is fairly easy to determine your desired sample size.
