ACT Preparation / Unit 21 ACT 2006 short lesson, about 20 seconds
Descriptive and Hypothesis-Based Science
Captions available
The idea
Descriptive science observes, explores and discovers, usually by induction; hypothesis-based science tests a proposed answer to a specific question, usually by deduction. Most research combines both.
In practice
Cataloguing the insects in a meadow is descriptive; testing whether mowing reduces their number is hypothesis-based.
Where people slip
The boundary is blurred: observations raise questions, and tests produce new observations.
