Probability provides a tool for public health professionals to assist populations in making healthier decisions. Consider for example how public health is concerned with issues such as the likelihood of incidence of certain infectious diseases, the effectiveness of interventions for chronic diseases, and the improvement of safety and health of communities. If for example, by educating the public about wearing a helmet when riding a bicycle may reduce the risk of serious head or brain injury by more than 80%, you are using probability to encourage better health choices.
Additionally, when conducting statistical analyses, some experimental design factors might contribute to the estimate of the necessary sample size. For this Discussion, consider the factors that might contribute to sample size.
Post an explanation of factors that might contribute to the relevance or irrelevance of sample size when conducting statistical analyses and why. Be specific and provide examples.
