When a study lacks statistical power, it is more likely to commit a Type II error, which is failing to reject a false null hypothesis. A Type I error is the rejection of a true null hypothesis, and a sampling error refers to errors in selecting a representative sample for the study. While both of these errors can occur in a study with low statistical power, the most common consequence is a Type II error.
