which of the following is a testable hypothesis?
To determine which statement is a testable hypothesis, it should be:
- Specific: Clearly define the variables that you’re investigating.
- Measurable: You should be able to observe or measure the outcomes.
- Testable/Observable: It must be possible to conduct an experiment or observation based on it.
Example of a Testable Hypothesis
Testable Hypothesis: “If plants are given fertilizer, then they will grow taller than plants that are not given fertilizer.”
Explanation:
- Specific: The hypothesis specifies “fertilizer” and “growth” (tallness) as variables.
- Measurable: You can measure plant height.
- Testable: You can conduct an experiment by applying fertilizer to some plants and not to others, then observing the results.
Non-Testable Hypothesis Example: “Music makes people happy.”
Explanation:
- This statement is subjective because “happiness” can vary widely between individuals and is not easily measurable in a scientific way without defining specific parameters (e.g., mood assessment tests).
Summary: Testable hypotheses are clear, measurable, and allow for observations or experiments. Always ensure your hypothesis meets these criteria.
