A statement that serves as an educated guess about how things work is called what?

• A. Hypothesis
• B. Control
• C. Diagnosis
• D. Antibiotic

Answer: (A)

A hypothesis is an educated guess about how things work that you can test. It makes a specific prediction about what you expect to observe under certain conditions and is testable—so data can either support it or refute it. In a medical detective context, you might propose that a particular pathogen is linked to a disease, predicting that samples from affected patients will show that pathogen more often than samples from healthy individuals. This kind of statement guides the investigation, directing what data to collect and how to evaluate results, and it can be revised if findings don’t fit. Other terms refer to different ideas: a control provides a baseline for comparison, a diagnosis identifies a disease in a patient, and an antibiotic is a drug used to treat bacterial infections.
