Which of the following describes a main feature of quantitative data?

The correct answer is that quantitative data is characterized by a lack of direct contact between the researcher and the participant. This feature is crucial because quantitative research typically relies on structured data collection methods, such as surveys or experiments, which are designed to produce numerical data that can be analyzed statistically. In these scenarios, researchers often use standardized instruments, allowing them to gather data from many participants simultaneously without the need for direct interaction. This approach helps ensure that data is collected in a consistent manner across different subjects, which is essential for producing reliable and generalizable results.

In contrast, methodologies that involve open-ended questions, small sample sizes, or rely on complex observations are more aligned with qualitative research. Qualitative approaches tend to emphasize in-depth understanding and often necessitate direct engagement between researchers and participants to capture nuances and subjective experiences, which is not a hallmark of quantitative data. Thus, the features of quantitative data distinctly highlight reliance on objective measurement and large-scale data collection strategies.
