Glossary - blinding


A process of concealing some aspect of an experiment from researchers and participants. In single-blind experiments, participants do not know which treatment they have been assigned to. In double-blind experiments, neither participants nor experimenters know which treatment the participants have been assigned to. In triple-blind experiments, as well as the participants and researchers, the statisticians analysing the results from an experiment are also blinded by being given treatment identifiers and not being told which identifier refers to which treatment. In software engineering we sometimes use blind-marking, where the marker does not know which treatment the participants adopted to arrive at their answers or responses.
