A decision you can investigate
- An interview study gives detailed accounts from six volunteers.
- Small numbers do not alone make qualitative research worthless.
Build the explanation
- Qualitative research examines meanings and experiences; quantitative research measures variables numerically.

Match the terms to their precise meanings.

Use these definitions in the particular context of Evaluating qualitative and quantitative research.
Work through the evidence
- An interview may reveal how people interpret an experience, but volunteer recruitment can shape whose perspectives appear.
- Compare themes with quoted evidence and reflect on the researcher's role, rather than judging credibility 可信性 only by sample size.

An interview may reveal how people interpret an experience, but volunteer recruitment can shape whose perspectives appear. Compare themes with quoted evidence and reflect on the researcher's role, rather than judging credibility only by sample size.
Test the limits
- The current HL methods paper differs from the 2027 source-based data paper.
- Do not apply experimental cause-and-effect standards indiscriminately to an inquiry about lived meanings.

The concept and worked evidence support these claims; the stated limits rule out the universal shortcut.
Use the terms precisely
- credibility: The trustworthiness of a research interpretation.
- transferability 可迁移性: The extent to which insights may apply in another context.

Write from eight bus accounts
- Eight volunteers describe how they revise on the bus. A reader says the study is worthless because eight is a small number, and also says it fails because it does not prove that bus noise causes lower grades.
- Say what the interviews can support and what standard does not fit them. This case is not the 2027 source-based paper.
Eight volunteers describe how they revise on the bus. A reader rejects the study because eight is small, and also because it does not prove that bus noise causes lower grades. What can the interviews support, and which standard does not fit?
Credibility is not sample size alone. The lesson asks whether recruitment and analysis support claims about the participants' experiences.
Which evaluation fits the bus-revision interviews?

The useful question is whether recruitment and the accounts support claims about these participants. A small number is not an automatic failure, and a causal test is the wrong standard.
