High f number
In most areas of optics, and especially in microscopy, the numerical aperture of an optical system such as an objective lens is defined by where n is the index of refraction of the medium in which the lens is working (1.00 for air, 1.33 for pure water, and typically 1.52 for immersion oil; see also list of refractive indices), and θ is the half-angle of the maximum cone of light that … Web11 de mai. de 2024 · The higher the F-value in an ANOVA, the higher the variation between sample means relative to the variation within the samples. The higher the F-value, the lower the corresponding p-value. If the p-value is below a certain threshold (e.g. α = .05), we can reject the null hypothesis of the ANOVA and conclude that there is a statistically ...
