What term refers to an educated guess that can be tested?

The term that refers to an educated guess that can be tested is a hypothesis. A hypothesis is a specific, testable prediction about the relationship between variables. In scientific research, it serves as a basis for experimentation and investigation, allowing researchers to collect data and draw conclusions.

The hypothesis is formulated based on existing knowledge and observations, enabling scientists to explore new ideas and validate or refute them through systematic experimentation. In contrast, a theory is more comprehensive, built up from many tested hypotheses and generally accepted explanations, not merely an initial guess. A postulate is an assumption made without proof to serve as a basis for further reasoning, typically not testable by experimentation in the same way as a hypothesis. Inference involves conclusions drawn based on evidence and reasoning, rather than an initial statement that invites testing.
