Effect Size in Single-Case Research: A Review of Nine Nonoverlap Techniques
Peer reviewed Peer reviewed
Direct linkDirect link
Parker, Richard I.; Vannest, Kimberly J.; Davis, John L. – Behavior Modification, 2011
With rapid advances in the analysis of data from single-case research designs, the various behavior-change indices, that is, effect sizes, can be confusing. To reduce this confusion, nine effect-size indices are described and compared. Each of these indices examines data nonoverlap between phases. Similarities and differences, both conceptual and…

Median-Based Overlap Analysis for Single Case Data: A Second Study
Peer reviewed Peer reviewed
Direct linkDirect link
Parker, Richard I.; Hagan-Burke, Shanna – Behavior Modification, 2007
This article takes a further look at the percentage of data points exceeding the median (PEM) analysis method for single-case research data, first presented in this journal by Hsen-Hsing Ma. Ma examined the relationship between PEM and the established percentage of nonoverlapping data (PND) and then applied PEM in a meta-analysis of 61 data sets,…

An Alternative Method for Quantitative Synthesis of Single-Subject Researches: Percentage of Data Points Exceeding the Median
Peer reviewed Peer reviewed
Direct linkDirect link
Ma, Hsen-Hsing – Behavior Modification, 2006
The purpose of the present study is twofold: (a) to compare the validation of percentage of nonoverlapping data approach and percentage of data points exceeding the median of baseline phase (PEM) approach, and (b) to demonstrate application of the PEM approach in conducting a quantitative synthesis of single-subject research investigating the…
