Vastatietoja

Vastatietoja is a Finnish term used to refer to data that describe responses to questions, surveys, or other information-collection instruments. The word is formed from vastata (to answer) and tieto (data or information), and in plural form it appears as vastatietoja. In statistics, market research, and information systems, vastatietoja denotes response data gathered from respondents or users, as distinct from input data such as sensor readings or operational logs. Typical components include the actual answers, ratings, and qualitative comments, as well as metadata such as timestamp, method of collection, or respondent segment.

Use and applications: Vastatietoja are analyzed to understand opinions, experiences, or outcomes, to identify trends, and to support decision making. They may be processed, coded for quantitative analysis, or analyzed qualitatively. In research workflows, they are often linked with other data sources to enable cross-tabulation or segment analysis, while preserving data integrity and privacy.

Data governance and privacy: When handling vastatietoja, organizations must follow applicable data protection rules. Anonymization or pseudonymization is commonly applied, and access is restricted to authorized personnel. Consent and transparency are important, particularly for sensitive topics, and data minimization principles should guide collection and storage.

Limitations: The quality of vastatietoja depends on survey design, sampling, response rates, and respondent honesty. Potential biases, such as nonresponse, social desirability, or measurement error, should be acknowledged in interpretation.
