ACCA Applied Knowledge · Management Accounting · Sampling methods
An auditor of a management information system wants to test the opinions of users. She selects a few users she considers to be typical and knowledgeable, using her own judgement. Which method is this?
This is judgemental, or purposive, sampling. The auditor uses her own judgement to select users she regards as typical and knowledgeable, so selection is not random. Snowball sampling would require respondents to suggest further participants, and random sampling would give each user a known chance.
