Question

Which statement best describes a testable hypothesis?

1) It is an assumption which includes a value judgment by the experimenter.
2) It is an expression of a relationship between observable and measurable variables.
3) It is a statement that has no basis for comparison.
4) It is a general explanation based on large amounts of collected data.

Answer 1

A testable hypothesis is an expression of a relationship between observable and measurable variables, which can be tested and potentially falsified through experimentation.

Step-by-step explanation:

The statement that best describes a testable hypothesis is "It is an expression of a relationship between observable and measurable variables." This aligns with the fact that a hypothesis must be testable via experimentation or observation by offering a conjectural statement about the relationship between two or more variables. Additionally, it is crucial for a hypothesis to be falsifiable, meaning it can be disproven by experimental results. A testable hypothesis often takes the form of an if-then statement, which helps to structure experimentation and guides the scientific investigation process.
