Explanation:

Pregunta 25

Case studies focus on a single or a few cases (like a person, group, or event). Since they don't study a large, representative sample, the findings (information learned) may not be generalizable to the wider population. Let's analyze other options: Defining dependent variables isn't uniquely hard for case studies; case studies aren't generally too expensive (compared to large - scale experiments/surveys); and while they have details, good researchers can organize them, so the "losing track" claim is not a core problem.

In ethical experimental research on humans, the principle of non - maleficence (or beneficence) requires researchers to protect participants from needless harm and discomfort. Let's check other options: Informed consent has exceptions (e.g., in some deception - based research with debriefing); personal info of participants should be kept confidential (not revealed in journals); and participants don't always need to know the hypothesis (e.g., in some studies with deception, but with debriefing later).

Answer:

The information learned may not apply to the wider population
