  • Q9
    What is a common purpose of scientific surveys compared to experiments?
    Surveys are conducted exclusively in laboratories.
    Surveys primarily focus on collecting quantitative data only.
    Surveys are used to test hypotheses under controlled conditions.

  • Q10
    What is an important benefit of observational studies compared to experiments?
    Observational studies require a rigorous control group.
    Observational studies are always more conclusive than experiments.
