World class computing and information science research at Strathclyde...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by University of Strathclyde researchers, including by researchers from the Department of Computer & Information Sciences involved in mathematically structured programming, similarity and metric search, computer security, software systems, combinatronics and digital health.

The Department also includes the iSchool Research Group, which performs leading research into socio-technical phenomena and topics such as information retrieval and information seeking behaviour.

Abstract

Presents guidelines for users of the simple Yes/No signal detection experiment who want to design their experiments to ensure a given precision for estimators of d. Additionally, simulations of small-scale Yes/No and rating-method experiments are employed to investigate when the use of asymptotic results is justified. The way in which the pay-off matrix for the Yes/No experiment may be manipulated to optimize precision is demonstrated. Large experiments may be needed to provide precise unbiased estimation of d, with sampling distributions that are not appreciably skewed.
