What is the term for first-hand information collected specifically for the purpose of a research study?

The term for first-hand information collected specifically for the purpose of a research study is referred to as primary data. This type of data is gathered directly from original sources through methods such as surveys, interviews, experiments, or observations. The key aspect of primary data is that it is specifically tailored to address the research question at hand, which makes it highly relevant and accurate for the study's objectives.

In contrast, secondary data refers to information that has already been collected and published by others, often for purposes unrelated to the current research. Tertiary data is a more abstract summary of secondary data, such as encyclopedias or databases, that compile and organize various sources rather than providing firsthand insights. Qualitative data involves non-numeric information that describes qualities or characteristics, which can originate from both primary or secondary sources.

The clarity and specificity of primary data make it essential for researchers looking to draw conclusions that are directly linked to their specific inquiries or hypotheses.
