Final answer:
A qualitative audit examines the effectiveness of an agency's advertising program implementation and results through methods such as interviews and focus groups.
Step-by-step explanation:
A qualitative audit focuses on the agency's efforts in planning, developing, and implementing the client's advertising programs and considers the results achieved. Unlike quantitative data, which would focus on numerical data such as the interest rate charged on the financial aid, a qualitative audit involves in-depth interviews, focus groups, and/or analysis of content sources to assess the program's quality and effectiveness.
An example can be seen in the work of community psychologist evaluators who assess programs for fidelity, housing retention, and cost-benefit analysis using interviews and surveys.
