WebI know that dF/F = ( F (t) - F0)/F0 and that F (t) is the fluorescent value at a given time and F0 is the resting fluorescence value, but for my particular system I am unsure how to calculate the ... WebF-statistics are the ratio of two variances that are approximately the same value when the null hypothesis is true, which yields F-statistics near 1. We looked at the two different variances used in a one-way ANOVA F-test. Now, let’s put them together to see which combinations produce low and high F-statistics.
