The sample size is the aspect of a study that can be easily changed to increase power. Increasing sample size in a study can lead to a larger effect size and increased power, even if the effect size cannot be manipulated by the experimenter. Beta level refers to the probability of making a Type II error, which is not directly related to power. Population parameters and sample mean are fixed values that cannot be changed once the sample has been collected.
