Final answer:
The distinctive feature of investigative consumer reports is that B) they provide information about a person's character and reputation. Case study results are typically not generalizable.
Step-by-step explanation:
The unique characteristic of investigative consumer reports compared to consumer reports is B. They provide information about a customer's character and reputation.
Investigative consumer reports go beyond basic credit history and financial information to include details about a person's character, general reputation, personal characteristics, and mode of living.
These are typically obtained through personal interviews with neighbors, friends, or associates. Unlike traditional consumer reports, these may offer a more subjective view of an individual's personal information.
When referring to case study results, b. Its results are not generally applicable is the correct description. Case studies provide in-depth analysis of a specific individual, group, situation, or event. They are highly detailed and contextual, but because they focus on one specific case, their results cannot be generalized to a broader population.
In terms of research and gathering information, compared to primary research like surveys or interviews, secondary data is advantageous due to its nonreactive nature. It does not require direct contact with subjects and therefore doesn't influence or alter the behavior of those being studied.
