The one way to increase statistical power without increasing the chance of making an incorrect statistical decision is by increasing the effect size.

Here's why:

1. Increasing beta levels: Beta is the probability of making a Type II error (failing to reject the null hypothesis when it is false). Increasing beta levels would actually decrease statistical power, not increase it.

2. Increasing population variance: This would make the data more spread out and could make it harder to detect a true effect, thus it could decrease statistical power.

3. Decreasing sampling error: This could increase statistical power, but it could also increase the chance of making an incorrect statistical decision (Type I or Type II error) because it could lead to overconfidence in the results.

4. Increasing the effect size: This means increasing the difference between the groups you are comparing. A larger effect size can make it easier to detect a true effect, thus increasing statistical power, without increasing the chance of making an incorrect statistical decision.
