Question 1
-
You are working on a clinical trial data set in SAS, and you need to create a new variable that captures the number of days since the start of the study. The study start date is available as an automatic variable called `Study_Start_Date`, and each patient's visit date is recorded in a variable called `Visit_Date`. Which of the following code snippets correctly calculates the new variable `Days_Since_Start`?
Answer: A

Question 3
-
Suppose you are working on a project that requires creating a customized table that is not readily available from any SAS procedures, but you can generate the needed statistics. You need to capture these statistics in a dataset for further manipulation. Which ODS OUTPUT destination would you use to redirect the output of PROC MEANS to capture the necessary summary statistics in a SAS dataset?

Question 5
-
During a clinical trial, data were collected on a nominal categorical variable indicating patients' blood type (Type A, Type B, Type AB, Type O). The goal is to analyze the distribution of blood types among patients who experienced an adverse event versus those who did not. Which of the following statistical methods BEST suits the objective of comparing the distribution of a nominal categorical variable across two independent groups?
Answer: D
