Tom is doing a statistical study into the amount of homework received by Year 7 and Year 11 students in his school. Write down a hypothesis Tom could use.
How to approach this question
1. Understand what a hypothesis is: a testable statement about the relationship between variables.
2. Identify the groups being compared: Year 7 students and Year 11 students.
3. Identify the variable being measured: amount of homework received.
4. Formulate a statement that predicts a difference or relationship. It should be specific and clear.
5. A good hypothesis could state that one group receives more, less, or a different amount of homework than the other.
6. Example: "Year 11 students receive more homework than Year 7 students."
Full Answer
Year 11 students receive more homework on average than Year 7 students.
A hypothesis is a precise, testable statement of what the researcher predicts will be the outcome of the study. In this case, Tom is comparing the amount of homework for two different year groups. A suitable hypothesis must make a clear comparison. For example:
- "Year 11 students receive more homework per week than Year 7 students."
- "There is a difference in the average amount of homework received by Year 7 and Year 11 students."
The statement must be a prediction that can be confirmed or refuted by collecting and analysing data.
Common mistakes
✗ Writing a question (e.g., "Do Year 11s get more homework?"). A hypothesis must be a statement.
✗ Vague statements (e.g., "Homework is different for year groups"). It should be more specific.
✗ Stating an aim (e.g., "I want to find out about homework").
