Epidemiologists control for variables such as confounding and random error by carefully developing research studies. Although there are not guarantees to eliminate or reduce all possible errors, it is important to minimize their effects.

For this Discussion, review your readings from this week. Then addressing the following:

• Identify the role of p-values and confidence intervals within epidemiologic research and provide examples of how these are used to interpret research findings.
• Discuss the effect sample size has on p-values and confidence intervals and how this affects interpretation of statistical results.
