Which research method is primarily used for collecting data for useable statistics?

1. Qualitative Analysis

2. Statistical Sampling

3. Quantitative Research

4. Ethnographic Study

The correct answer is: Quantitative Research

Quantitative research is primarily used for collecting data that can be analyzed statistically, making it suitable for generating usable statistics. This approach focuses on measurable data and often involves surveys, experiments, or structured observations that can yield numerical outcomes. The use of statistical tools to analyze such data allows researchers to identify patterns, relationships, and trends, thus facilitating objective analysis and enabling the formulation of generalizations about a population based on the sample studied. In contrast, qualitative analysis typically focuses on understanding concepts, experiences, or phenomena in depth, often using open-ended questions and interviews that provide rich, descriptive data rather than numerical statistics. Statistical sampling relates to the technique of selecting a subset of individuals from a larger population for the purpose of statistical inference, but it is not a research method in itself; rather, it supports quantitative research. Ethnographic studies involve immersive observation and interaction within a cultural or social group, emphasizing detailed contextual understanding rather than gathering quantitative data.
