Programs for the Collection and Analysis of Observational Data.
Roberts, William L.
Although videotape is the preferred method for recording behavior, there are many natural settings in which it is impractical or too intrusive. The ability to collect data in such settings and in real time has been enhanced by the advent of light, powerful laptop computers. This poster (with paper) describes a set of eight programs (developed in British Columbia) for collecting and analyzing focal-individual data (i.e., events and interactions) and scan-sample data (states) on such IBM-compatible machines. These computer programs can accommodate almost any user-specified set of codes, including codes for simultaneous events. Reliabilities (percent agreement and kappa), rates, frequencies, cumulative time (time-budget data), and conditional probabilities with z-scores and exact binomial probabilities can be generated. Binomial probabilities test the null hypothesis that the conditional probability is at chance levels. General contingency across the entire set of codes can be assessed by log-linear analysis, and specific patterns of contingent behavior can be identified automatically. Four figures illustrate the discussion. (Contains 3 references.) (Author/SLD)
