Answer:
A survey of student satisfaction conducted at the end of the course is not a cross-sectional data set.
Cross-sectional data refers to data collected from a sample of individuals or units at a specific point in time. In this case, the survey of student satisfaction is conducted at the end of the course, capturing the opinions and satisfaction levels of a specific group of students at that particular time. This data set does not provide information about different time periods or trends across time.
On the other hand, the monthly survey of consumer confidence, the national census conducted every 5 or 10 years, and the weekly data on average temperature are all examples of cross-sectional data sets. They collect information from different individuals or units at different points in time, allowing for comparison, analysis, and identification of trends over time or across different groups.
