Final answer:
Qualitative researchers ensure the trustworthiness of their findings through triangulation, which means using multiple data sources or methods. This provides a more nuanced understanding of the topic of study, ensuring greater accuracy and validity of the research findings.
Step-by-step explanation:
How do qualitative researchers ensure the trustworthiness of their findings? The correct answer is c) Triangulation. Qualitative researchers use methods such as triangulation to ensure the accuracy and trustworthiness of their findings. Triangulation involves using multiple data sources or methods to study one topic, which can help validate the research. Qualitative sociology often employs tools like in-depth interviews, focus groups, and content analysis to understand human behavior through detailed, narrative data rather than through quantitative data which involves statistical analysis. Another key concept in the field of sociology is validity, which refers to the degree to which a sociological measure accurately reflects the topic of study. This is crucial in ensuring that the findings or conclusions drawn are genuinely representative of what is being investigated. It's important to distinguish this from the statistical measures used in quantitative research, which are not the primary methods of establishing trustworthiness in qualitative research.
