- Please employ appropriate SAS procedures to produce descriptive statistics and p-values that would allow you to fill in the table below.
- Use the Dataset EPI626_Assign6_F2019.
- Descriptive statistics
- For normally distributed continuous variables, present mean and standard deviation. For continuous variables that are not normally distributed, present median and IQR.
- For categorical variables, present number (count) and proportion (%).
- Hint: You may have to recode some of the categorical variables.
- P-values
- If comparing means from two groups, use T-test
- If comparing means from three groups, use ANOVA.
- If comparing distribution of non-normally distributed continuous variables, use non-parametric tests.
- If comparing proportions from two or more groups, choose between Chi-Square or Fisher’s Exact test, depending on expected cell sizes.
- Hint: you will have to recode age from a continuous variable into a categorical variable.
- Fill in the number of observations in each age group at the top of the table.N = (???)
- Please submit SAS code, log, and output.
