This article outlines Indigenous data collection as a methodology that expands a sampling frame by using tribal Indigenous cultural knowledge, such as creation stories like those of the Cocopah and Quechan nations, to address limitations found in the methodological quality of Native American survey data in currently available datasets. Indigenous quantitative methodology and methodological limitations in existing government and institutional datasets are outlined (Walter & Andersen, 2013), and validities described by Shadish, Cook, and Campbell (2002) and the Standards for Educational and Psychological Testing (AERA et al., 2014) are explored. The conclusion presents the advantages of using Indigenous data collection to provide a sampling frame that highlights the use of Indigenous quantitative methodology.
