A statistical study of the spot-plate technique was made for the purpose of establishing an acceptable counting range. The organism used in these studies was Micrococcus lysodeikticus. Standard deviations and coefficients of variation were computed for counts ranging from 20 to 440. The lower and upper limits for acceptable counts, based on coefficients of variation of 10 and 5.8, respectively, were chosen as 100 and 300.
为确定可接受的计数范围,对点滴平板技术进行了统计学研究。这些研究中使用的生物体是溶壁微球菌。计算了20至440范围内计数的标准差和变异系数。基于变异系数分别为10和5.8,将可接受计数的下限和上限分别选定为100和300。
