• A) microcosms.
• B) approximate systems.
• C) natural treatments.
• D) experimental units.

Calculate, analyze, and interpret quartiles and the interquartile range within datasets.

Definitions:

Confounded

Confounded refers to a situation in research where the effect of one variable cannot be separated from the effect of another, making it difficult to determine the cause of any observed changes.

Experimental Method

A research method involving the manipulation of variables to establish cause-and-effect relationships.

Cause-And-Effect

The principle that suggests every event (cause) leads to a certain result (effect), underlining the relationships between actions and outcomes.

Natural Setting

A real-world environment where behavior and events occur spontaneously, outside of a controlled or laboratory setting.
