Statistical power refers to the ability of a study to detect a true effect if it exists. A study with a statistical power of 0.5 has a lower ability to detect a true effect, meaning it is more likely to result in a Type II error, which is failing to reject a false null hypothesis. Therefore, the study with a statistical power of 0.8 is more likely to produce a statistically significant finding, but it does not necessarily give a more precise estimate of the effect.
