We are going to be looking at the standard deviation function where we are still working with the same Framingham dataset using the following variables: age, systolic blood pressure, diastolic blood pressure, use of anti-hypertensive medication, current smoker, total serum cholesterol, mg/dL, body mass index (BMI), and diabetes, by determining the means for each risk factor. We will also be creating a table that summarizes the results from your analysis. There is so much to consider in performing this analysis so rather than describing it in words I want to offer some good sites that will help you with your questions.
