Question

When researchers cannot randomly assign participants and manipulate conditions in the real world, they can sometimes compromise by conducting __________ experiments

Answer 1

The answer is natural experiments.

Step-by-step explanation:

In natural experiments, the groups of participants are not controlled by the researchers. They are often done when lab experiments would interfere with the validity of the study, or when applying it would be unethical (for example, experiments related to diseases are often studied in a natural environment).

Natural experiments are recorded through observation. They usually seek to understand the effects of an environmental factor in a sample population.
