title: A brief account of statistical tests for single-case research with persons with developmental disabilities.
abstract: Education and rehabilitation research with persons with developmental disabilities is often based on single-case designs (with small numbers of ordinal data points collected at irregular intervals) and relies upon graphic display and visual inspection of the data. This paper (a) provides a brief account of some statistical tests, which may serve to supplement the visual inspection process and (b) underlines some of their strengths and limitations to help education and rehabilitation personnel make a reasonable choice among them.
