Self-selected and randomly selected respondents in a computer network survey

Abstract

During administration of a computer network survey of oceanographers, additional persons spontaneously asked to participate. Using comparisons of the random sample with the self-selected group, sought to understand this motivated responding and the biases entailed. Motivation to respond or self-select seems due partly to ease of response and partly to a desire to give voice. (Abstract amended)
