统计功效是当零假设为假（II类错误）时接受零假设的概率。本研究报告报告了1990年至1999年发表在《国际商业研究》、《管理国际评论》、《管理学会杂志》和《战略管理杂志》上的国际商业研究的统计力量分析结果。结果表明，虽然平均统计功率与其他学科相比是高的，这是足够的，只有大的效果大小（ES）。只有发表在《国际商业研究杂志》和《管理学院杂志》上的研究才能达到足以适用于中型和大型ES的平均统计能力水平。尽管如此，在国际商业研究中，小型ES（92%）和中型ES（45%）犯第二类错误的可能性仍然很高。此外，国际商业研究人员没有明确提到或使用统计力量，本说明旨在改变这一弱点。
Statistical power is the probability of accepting the null hypothesis when it is false (type II error). This research note reports the results of a statistical power analysis of international business research published in the journal of International Business Studies, Management International Review, the Academy of Management Journal, and the Strategic Management Journal from 1990 to 1999. The results show that, although average statistical power is high compared with other disciplines, it is sufficient only for large effect sizes (ESs). Only studies published in the Journal of International Business Studies and the Academy of Management Journal achieve average statistical power levels that are sufficient for both medium and large ESs. Still the observed likelihood of committing type II errors in international business research is very high for small ESs (92%) and high for medium ESs (45%). In addition, statistical power is not explicitly mentioned or used by international business researchers, a weakness that this note is designed to change.
