For example, if you wanted to examine whether first-time moms who have an elective induction are more likely to have a cesarean birth than first-time moms who go into labor naturally, the independent variables would be elective induction and go into labor naturally (because they are the variables that vary) and the outcome variable is cesarean section. Even if you find a strong relationship between elective inductions and an increased likelihood of cesarean birth, you cannot state that elective inductions cause cesarean births because we have no control over the variables.
