Answer
a) The provided study is cross-sectional (information collected at a specific point in time.)
b) An explanatory variable is a variable that affects the value of the response variable. Researchers studied the association between method of delivery and cost of delivery. In the provided study, the delivery scenario will tell about the cost of delivery. This means that the explanatory variable affects the value of the response variable.
c) In the provided study, researchers studied the method of delivery and cost of delivery for low-risk mothers for first-time delivery. Researchers considered three scenarios of delivery. The first scenario of delivery is caseload midwifery, the second scenario is standard hospital care, and the third one is private obstetric care. Here, method of delivery and cost of delivery are response variables. Cost of delivery is a quantitative variable because cost is a numerical value. The method of delivery describes the delivery scenario (quantitative).
