Mastering the Basics of Visual Analysis

Katie Wolfe and Timothy A. Slocum

Visual analysis of data is a cornerstone of single-subject research. Yet some researchers have found that experts often disagree about what constitutes an intervention effect. This potential lack of consistency across visual analysts can have negative implications for both research and practice. This tutorial offers a systematic, evidence-based procedure for training individuals to conduct valid and reliable visual analyses of single-subject data. It features extensive discrimination training and practice opportunities; adaptive instruction and remediation for errors; and full audio narration in a self-paced, mobile-friendly format.
