Question

Quizplus · Accepted Answer

Manipulative experiments involve deliberately manipulating one or more variables in a system to see how it affects the other components. This allows scientists to directly assess cause-and-effect relationships and establish a reliable understanding of how a system operates. Manipulative experiments can be done in a laboratory or in the field, depending on the type of system being studied.
