Raman spectroscopy is the measurement of the wavelength and intensity of inelastically scattered light from molecules.aman spectroscopy is the measurement of the wavelength and intensity of inelastically scattered light from molecules.
1. Average can be in mean (arithmetic mean), median, or mode. Mean is basically a form of describing an average of the sample. 2. Mean can be in many various types too, but only the arithmetic mean is considered as a form of average.
The median is the ((n + 1)/2)th item, where n is the number of values. For example, for the list {1, 2, 5, 7, 8}, we have n = 5, so the median is the ((5 + 1)/2)th item.
