Question

what are the key features of experimental methods?​

Answer 1

Answer:

In general, designs that are true experiments contain three key features: independent and dependent variables, pretesting and posttesting, and experimental and control groups. In a true experiment, the effect of an intervention is tested by comparing two groups.

Answer 2

The experimental method involves the manipulation of variables to establish cause and effect relationships. The key features are controlled methods and the random allocation of participants into controlled and experimental groups.
