mean±s.e.m.和mean±sd存在区别，主要体现在其代表的意义和计算方式上。mean±s.e.m.代表平均值加减标准误。其中，“mean”指的是平均值，反映了数据的集中趋势；“s.e.m.”即“standard error of the mean”，即平均数的标准误，反映了...
Chebyshev's inequality is used when there is no information regarding the distribution of the population. The purpose of Chebyshev's inequality is to calculate the minimum proportion of the data within certain standard deviations of the mean. Answ...
L4 stage worms were transferred to the mNGM plates withE. coliOP50 orP. freudenreichiiand fed bacteria for 14 days. After 14 days, lipofuscin was measured by assessing autofluorescence using a confocal microscope. (A) Fluorescence of lipofuscin in worms fedE. coliOP50 andP. freudenreichiion d...
The distribution of mean values enables the calculation of a 95% confidence interval on the mean compositions reported in this paper. Note that the distribution of means is Gaussian, even though the initial population is decidedly non-Gaussian (Figure 4a). The global mean shown here of 32±...
