The design of one factor with k levels (k ≥ 3) refers to the research that only involves one experimental factor with k levels (k ≥ 3), and there is no arrangement for other important non-experimental factors. This paper introduces the estimation of sample size and testing power for quantitative data and qualitative data having a binary response variable with the design of one factor with k levels (k ≥ 3).
具有k个水平（k≥3）的单因素设计是指仅涉及一个具有k个水平（k≥3）的实验因素，且未对其他重要的非实验因素进行安排的研究。本文介绍了具有k个水平（k≥3）的单因素设计对于定量数据以及具有二元响应变量的定性数据的样本量估计和检验效能。
