This is a companion document to the Week 3
Internal Validity and External Validity PowerPoint.
Figure 1 is a graphic of Onwuegbuzie’s “Quantitative Legitimation Model”
Table 1 is a table containing descriptions of the 50 dimensions of internal and external validity threats across three stages of the quantitative research process, identified in Onwuegbuzie’s Quantitative Legitimation Model.
The table provides the following details about each of the 50 dimensions of internal and external validity threats identified in Onwuegbuzie’s “Quantitative Legitimation Model”:
·
Stage of the Research Process (i.e., Data Analysis, Data Interpretation, Research Design/Data Collection)
·
Type of Threat (i.e., internal validity or external validity)
·
Specific Validity Threat (i.e., dimension)
·
Description of the validity threat
