Roper (2020) conducted a critique of the Larson et al. (2019) study of the accuracy and confidence of data collected using systematic and random sampling designs. Roper (2020) did not provide a data set but speculated that the Larson et al. (2019) conclusions likely reflected differences in the number of plants evaluated at each plot and the low number of independent observers rather than the sample design. Our random sampling design employed multiple randomly located quadrat locations and measured multiple plants (> 5) that were averaged within the plot to represent plot characteristics. Data collected in this fashion fulfilled assumptions intrinsic to and necessary for statistical analysis using plot data as observations. Thus, the statistical observations reported in the original paper are valid.

罗珀（2020）对拉森（Larson）等人的评论。（2019）研究使用系统和随机抽样设计收集的数据的准确性和可信度。Roper（2020）没有提供数据集，但推测是Larson等人。（2019）的结论可能反映了每个样地评估的植物数量的差异以及独立观察员的数量较低，而不是样本设计的差异。我们的随机抽样设计采用了多个随机定位的四边形位置，并测量了多个植物（> 5），这些植物在地块内取平均值以表示地块特征。以这种方式收集的数据满足了使用绘图数据作为观察数据进行统计分析所固有和必要的假设。因此，原始论文中报道的统计观察是有效的。
