Which of the following demonstrates ethical behavior in research?

Considering participant wellbeing demonstrates ethical behavior in research because it prioritizes the rights, safety, and welfare of individuals involved in the study. Ethical research practices require that researchers ensure that participants are treated with respect and dignity, and this includes taking into account their physical, emotional, and psychological wellbeing throughout the research process. By focusing on participant wellbeing, researchers can also foster trust and cooperation, which are essential for obtaining valid and reliable results.

In contrast, asking leading questions can bias the data collected, as it may influence participants' responses. Suppressing irrelevant data is problematic because it may lead to a distortion of findings and conclusions, reducing the integrity of the research. Lastly, choosing a biased sample undermines the validity of the research outcomes, as it prevents the generalizability of results and may misrepresent the population being studied. Thus, emphasizing participant wellbeing is a foundational aspect of ethical research practices.
