Determine whether the study depicts an observational study or a designed experiment.

Understand the Problem

The question is asking to determine whether each provided study scenario is an observational study or a designed experiment. Each question describes a different study, requiring an understanding of the definitions of observational studies and experiments to classify them appropriately.

More Information

Observational studies measure variables without intervention, while experiments involve manipulating variables to observe effects. This distinction helps in understanding causation versus correlation.

Tips

A common mistake is confusing correlation in observational studies with causation, which is typically more assessable through designed experiments.
