As the sample size increases, the standard error of the mean decreases, making the estimate more precise. This increase in precision and sample size leads to an increase in the power of statistical tests, which is the ability to detect an effect if there is one, thus decreasing the probability of a Type II error (failing to reject a false null hypothesis).
