Which of the following is not a qualitative data example?

The reasoning behind identifying households with water-sealed toilets as not being a qualitative data example lies in the nature of qualitative versus quantitative data. Qualitative data is descriptive and conceptual, often gathered through interviews, observational studies, or open-ended surveys, and it focuses on understanding perceptions, experiences, and social phenomena.

In this context, the other options involve collecting subjective reflections or insights about behaviors, attitudes, and social structures. For instance, perceptions of mothers on nutrition, people's food habits, and the leadership structure in a community all rely on understanding the nuances of individual or group experiences, which are inherently qualitative.

In contrast, the characteristic of households with water-sealed toilets is straightforward and typically involves measurable data. This information can be easily counted or categorized, aligning it with quantitative research, which deals with numerical data and statistics. Thus, the distinction is clear: the correct answer represents data that cannot be analyzed qualitatively in the same way as the other examples.
