This study explored some practical issues for single-case researchers who rely on visual analysis of graphed data, but who also may consider supplemental use of promising statistical analysis techniques. The study sought to answer three major questions: (a) What is a typical range of effect sizes from these analytic techniques for data from…

The heuristics guide students' judgments about significance, generalizability, cause-and-effect, and strength of independent-dependent variable…

This paper presents findings from an historical investigation of visual literacy, a unique aspect being that the approach relied on the marriage of two disciplines--geography and history--which study change over time. Maps and their interpretation of data by cartographers tend to provide a foundational context that can illuminate past and present…
