Sampling and sample size in B2B marketing: Current practices and recommendations
通过回顾2013-2023年B2B营销三大顶级期刊的文献，分析了抽样实践现状，发现定量研究增多但方法论证不足，并提出了最佳实践建议，如结合主数据和二手数据、进行功效分析等。
Sampling procedures and sample size have the potential to improve the accuracy and efficiency of business-to-business (B2B) marketing research, as well as provide added statistical rigor to research. Therefore, justifying the rationale for sampling is useful in reducing uncertainty and accomplishing high standards. This paper aims to understand the sampling approaches applied in B2B marketing through a literature review of the three most reputable journals focused on this area in the 2013–2023 period. Furthermore, the paper also aims to develop a set of best practices. Results suggest that, although quantitative research is gaining presence in B2B marketing literature, there are different areas of improvement in terms of justification, explanation of the methodology, and the use of data. Achieving a minimum sample size along with the combination of primary and secondary data, and justifying the sampling, data collection, and methods used through statistical lenses, refraining from simplistic arguments, are not only valuable sources of detailed information, but can also increase confidence in quantitative research. • Quantitative research has been gaining presence in B2B marketing journals last decade. • The median sample size identified during the period of analysis is 272.5. • Sampling processes should be explained and justified with power analyses. • Combining primary and secondary data and mixed methodologies can strengthen B2B research. • New sampling methods can arise from interdisciplinary collaborative efforts.
