Privacy Policy | Terms of Use | Login, Using Statisticsin FCS Express to report MFI, In general, the geometric mean statistic is only useful for positive values. If you're looking at a non-normally distributed population - a population curve that shows asymmetry on histogram, or a pronounced shoulder - use the geometric mean. In most cases, the measurement of "relative fluorescence intensity" is adequate, where the fluorescent channel number that best approximates the average fluorescence of one population is compared with the same value from a second population labeled with the same reagent.

I'm just measuring the total amount of DNA in one wt cyanobacteria spp, and comparing with the total amount of DNA with a modificated strain that is suposed to have more DNA (so I should detect more DNA per cell). Hoping this will help, Claude, You have MFI buried deep in the add statistics option in flowjo vx u can set your gates and add the MFI, Yes, I made the meassurements in the same conditions (same culture state, same OD, same day, same setups on the instrument, etc). Fluorescence scoring was quantified using Fiji. Scaling choices will impact how the data is presented visually on the plot, but will not affect the statistical value. While the Mean might be most useful when used to describe normal distributions and not bi-modal or multi-modal data, the Median is a non-parametric statistic in that it is a better indicator of the central tendency of your data, regardless of the underlying data distribution.
