vasteosuus
Vasteosuus is a statistical term used in Finnish research to describe the proportion of people who provide a usable response to a survey or questionnaire relative to the number invited or eligible. In English, the term is often described as the response rate or response share. The concept is central to survey methodology because the level of response affects the precision of estimates and the potential for nonresponse bias.

Interpretation and limitations: A higher vasteosuus generally reduces sampling error but does not by itself guarantee
Applications: The term is commonly used in Finnish practice across contexts such as market research, public
