Hello, Dr. Mel We are creating a program to evaluate how the Action Committee Against Narcotics (ACAN) operates. I’m not sure how big of a sample size we’ll need for the survey. Please let me know if a large sample size is preferable.

I appreciate you asking.

Thank you for responding!

The power of a statistical test is significantly influenced by the sample size. The variance of the sampling distribution of the mean decreases as sample size increases. But keep in mind that a larger sample size also comes at a higher financial cost. Therefore, you can determine the sample size based on the funding for your research.
