Final answer:

A hypothesis needs to be testable and falsifiable to ensure validity in scientific research.


Explanation:

A hypothesis must be testable and falsifiable to ensure its validity. For example, a hypothesis like "All dogs are friendly" is testable as one can observe and interact with different dogs to gather evidence. On the other hand, a statement like "Some people like pizza more than others" is not specific and cannot be easily tested through objective measures.
