PUH 5302 CSU Determination and Confidence Intervals Presentation

In this unit, you learned how to determine sample size and estimate confidence intervals. For this assignment, you will create a PowerPoint presentation that further explores these concepts. In your presentation, you must include the following elements:

• a definition of point estimate, standard error, confidence level, and margin of error;
• a discussion of at least three major methods of determining sample sizes, comparing the different methods; and
• an explanation of the effects (advantages and limitations) of a small sample size, a very large sample size, and an adequate sample size on any research study.
