In the following four sections of this chapter ferromagnetic resonance (FMR), Brillouin light scattering (BLS) and nuclear magnetic resonance (NMR) will be described. Web1.3 Simple Random Sampling for Attributes. The method for SRS can be applied to estimate the total number, or proportion (or %) of units which possess some qualitative attribute. Let this subset of the population be C: Let Y i= 1 if i2C = 0 if i=2C and similarly for y i’s . Customary notation: = Y = P is the population proportion, Y = XN i=1 Y good company movie
