tiedonkeruulähteet

Tiedonkeruulähteet refer to the various origins or sources from which information can be gathered. These sources are crucial for research, decision-making, and understanding a given topic. They can be broadly categorized into primary and secondary sources.

Primary sources provide direct, firsthand evidence about an event, object, person, or work of art. Examples include original documents like diaries, letters, interviews, surveys, photographs, historical records, and empirical data collected through experiments or observations. They offer an uninterpreted view of the past or a phenomenon.

Secondary sources, on the other hand, interpret, analyze, or comment on primary sources. They are often one step removed from the original event or object. Common secondary sources include textbooks, articles, biographies, reviews, and scholarly analyses. They synthesize information from multiple primary sources to offer a broader perspective or argument.

Beyond this primary/secondary distinction, information can also be obtained from tertiary sources, which compile and summarize information from secondary sources, such as encyclopedias or bibliographies. The reliability and relevance of any information source must always be critically evaluated. Factors like author credibility, publication date, bias, and purpose play a significant role in determining the trustworthiness of a tiedonkeruulähde. Choosing appropriate and credible sources is fundamental to conducting sound research and forming accurate conclusions.
