Vastamismäär

Vastamismäär, often translated as "response rate" or "recruitment rate" in English, is a metric used in various fields, most notably in research and surveys, to quantify the proportion of individuals who participate after being invited to do so. It is calculated by dividing the number of actual respondents by the total number of eligible individuals who were contacted.

For example, in a survey research context, if 1000 people are invited to participate and 200 complete the survey, the vastamismäär would be 20%. A higher vastamismäär generally indicates a more successful recruitment effort and can lend greater confidence to the representativeness of the sample. Conversely, a low vastamismäär might raise concerns about potential non-response bias, where the characteristics of those who participate differ significantly from those who do not.

Factors influencing vastamismäär include the survey topic, the method of contact, the perceived burden on the respondent, incentives offered, and the reputation of the organization conducting the study. Strategies to improve vastamismäär often involve clear communication, user-friendly survey design, and appropriate follow-up procedures. The specific benchmark for an acceptable vastamismäär can vary significantly depending on the research discipline and the specific goals of the study.
