keräyskokeen

Keräyskokeen, often translated as a collection experiment or survey experiment, is a research methodology used in social sciences and market research to investigate the potential impact of question wording or survey design on respondent behavior. It is a type of experimental design embedded within a survey. The core principle of a keräyskokeen is to randomly assign different versions of a survey question or a set of questions to different subsets of respondents within the same sample.

By administering these variations, researchers can isolate and measure the effect of specific design elements, such as the phrasing of a question, the order in which questions are presented, or the response options offered. This allows for the identification of potential biases or influences that might otherwise go unnoticed in standard survey administration. For example, a researcher might test two different ways of asking about income to see if one phrasing leads to higher reported incomes than the other.

The data collected from these experimental groups is then statistically analyzed to determine if there are significant differences in the responses attributable to the manipulated survey features. This provides valuable insights for improving survey design, enhancing data quality, and ensuring that survey results accurately reflect the phenomena being studied. Keräyskokeen is particularly useful for understanding how subtle changes in survey instruments can affect perceptions, attitudes, and reported behaviors.
