A hypothesis is defined as which?

• A. A general aim.
• B. Detailed, precise, testable statement about relationships.
• C. Data collection method.
• D. Ethical approval.

Answer: (B)

A hypothesis is a precise, testable statement about the relationship between variables. It comes from theory and lets you predict what you expect to observe in your data, so you can test that prediction with your study design. This is why it’s distinct from a general aim, which is broad and vague, and from data collection methods or ethical approval, which describe how you carry out the study rather than what you expect to find. A good hypothesis specifies the variables, the expected direction of the relationship (if applicable), and is testable with measurable data, so analysis can confirm or refute it. For example, you might predict that more sleep leads to better recall, a statement that can be tested by measuring sleep and memory performance.
