采用相同样本的顺序设计，通过二维模型对混合方法研究进行分类，其中抽样设计根据每个研究成分的时间取向以及定性和定量样本的关系进行分组。对代表社会科学或健康科学9个领域的121项研究进行的定量分析显示，更多的研究采用并行抽样设计（66.1%），而不是顺序抽样设计（33.9%）。相同抽样设计最为普遍，其次是嵌套抽样、多层抽样和并行抽样。定性分析表明，在许多研究中，研究人员做出的统计概括并不充分，最终导致解释不一致，并导致代表性、合法性、整合和政治危机。
A sequential design utilizing identical samples was used to classify mixed methods studies via a two-dimensional model, wherein sampling designs were grouped according to the time orientation of each study's components and the relationship of the qualitative and quantitative samples. A quantitative analysis of 121 studies representing nine fields in the social or health sciences revealed that more studies utilized a sampling design that was concurrent (66.1%) than sequential (33.9%). Also, identical sampling designs were the most prevalent, followed by nested sampling, multilevel sampling, and parallel sampling, respectively. Qualitative analysis suggested that across a number of studies the researchers made statistical generalizations that were not sufficiently warranted-culminating in interpretive inconsistency and contributing to crises of representation, legitimation, integration, and politics.
