In the administration of quantitative research instruments it has been customary to use 'pencil and paper' forms, with the researcher distributing forms, collating the responses and supervising data entry into a structured database. The advancements in connected-computer technologies and statistical software applications offer quantitative researchers a more streamlined method for the collection, storage, manipulation and dissemination of data. These advancements have made it possible to dispose of, in appropriate studies, 'paper-and-pencil' instruments and manual data entry. However, the use of the internet, as with any method of collecting data, does have limitations and many of these are technical. This paper explores the technical issues associated with the development of connected-computer, quantitative instruments.
