Mean vs geometric mean flow cytometry

WebJan 3, 2024 · By its name, “Geometric” mean would indicate that it should represent a central tendency on data displayed graphically (i.e., originally on a pure log scale). In other words, if you were to graph a histogram on a log scale on paper, and cut it out, then the geometric mean would be that position where the balance point was. WebMar 19, 2013 · MFI is often used without explanation, to abbreviate either arithmetic mean, geometric mean, or median fluorescence intensity.
