Which aspect of qualitative research did Harriet Martineau significantly contribute to in her sociological studies?

Harriet Martineau made significant contributions to qualitative research, especially through her emphasis on the importance of understanding people's experiences and perspectives. She believed that to study society, researchers must look closely at how individuals live and interact in their everyday lives. For example, she conducted detailed observations and interviews, which allowed her to gather rich, descriptive data about social issues like gender and class. By focusing on these personal stories, she helped highlight the complexities of social life, making qualitative research a crucial method in sociology. Martineau's work showed that statistics alone cannot capture the full picture of human behavior, emphasizing the need for deeper insights into people's feelings and experiences.
