Answer 1

Cross-sectional data analysis involves observing different entities during the same time period.

Step-by-step explanation:

Cross-sectional data analysis involves observing different entities during the same time period. It is a type of research that collects data from a sample of subjects just once at a certain point in time. For example, if a researcher wants to study the average income of different age groups in a population, they would collect data from individuals of different ages at a specific time.
