Here is an open question from Tom's study: "How much do you earn? £____". Write down a problem with this question.

There are two main problems with this question: 1. **It is too personal/sensitive:** Many people consider their income to be private information and would be reluctant to disclose the exact amount to a researcher. This could lead to a high non-response rate or people giving inaccurate answers. 2. **It is ambiguous:** The question does not specify a time frame. "How much do you earn?" could be interpreted as per hour, per week, per month, or per year. This ambiguity means the data collected would be inconsistent and unusable. A better approach would be to use anonymous response boxes with income bands, for example: "[ ] Under £10,000 per year", "[ ] £10,000 - £29,999 per year", etc.
