Data Collection Techniques

Data collection is a component of research in all fields of study including physical and social sciences , humanities , and business. While methods vary by discipline, the emphasis on ensuring accurate and honest collection remains the same.

The goal for all data collection is to capture quality evidence that allows analysis to lead to the formulation of convincing and credible answers to the questions that have been posed.

Regardless of the field of study or preference for defining data quantitative or qualitative , accurate data collection is essential to maintaining the integrity of research. Both the selection of appropriate data collection instruments existing, modified, or newly developed and clearly delineated instructions for their correct use reduce the likelihood of errors occurring.

A formal data collection process is necessary as it ensures that the data gathered are both defined and accurate and that subsequent decisions based on arguments embodied in the findings are valid. Distorted findings result in wasted resources and can mislead other researchers into pursuing fruitless avenues of investigation; it may also compromise decisions, for example for public policy , which may cause disproportionate harm.

A checklist is a list of behaviors,characteristics,or other entities that te researcher is looking for. Either the researcher or survey participant simply checks whether each item on the list is observed, present or true or vice versa.

A rating scale is more useful when a behavior needs to be evaluated on a continuum. They are also known as Likert scales.
