HyperRESEARCH: A computer program for the analysis of qualitative data with an emphasis on hypothesis testing and multimedia analysis

Abstract

This paper describes a software program for Macintosh computers which assists with the analysis of qualitative data. HyperRESEARCH is a HyperCard-based application that allows for qualitative and quantitative analysis of textual, graphic audio, and video materials. HyperRESEARCH performs the following tasks: (1) The coding of text (of any length: a word, phrase, sentence, paragraph, etc.), graphics, coding of audio, video tapes using Tandberg computer controlled tape decks and several types of computer controlled video systems (video disc and video tape). A given segment of text, graphic, audio and video can be assigned multiple codes. (2) Retrieval of coded materials (text, graphics, audio and video segments) enabling the researcher to array all similarly coded material together. (3) The testing of propositions by performing Boolean searches on any code or combination of codes via the use of an expert system. (4) Hypothesis testing using artificial intelligence. The Expert System software technology uses production rules to provide a semi-formal mechanism for theory building and description of the inference process used to draw conclusions from the data. (5) A statistical option which allows for the simple analysis of coded data. The use of HyperRESEARCH as a methodological tool supports important advances in the validation, reliability and generalizability of qualitative data analysis.
