Statistics

Calculation for Comparing Populations (Staining Index)

This calculation can be used for normalizing the relationship between positive and negative populations to compare treated and untreated samples.

SI = (MFI_pos – MFI_neg ) / (2 x SD_neg) 

SI = staining index
MFI = median, geometric-mean, or mean fluorescence intensity
SD = standard deviation.

Note: Population average fluorescence intensity values can be skewed depending on the population distribution. Median fluorescence intensity is less skewed than geometric-mean fluorescence intensity and geometric-mean fluorescence intensity is less skewed than mean fluorescence intensity for log-normal populations (populations that look gaussian when plotted on a log scale).
