Study on Usage of Coefficient of Variation for Statistics of Magnetic Parameters of Samples

SUN Zhong-ren(Shenyang Institute of Geology and Mineral Resources,Shenyang 110033)  
In the past,the work on rock(ore) magnetic parameter measurement was not pay enough attention and most of work only measured magnetic parameter,sometimes seldom or even no measuring was done.Some of the work only statistically study the mean of magnetic susceptibility and magnetism,residual magnitude,not deeply study the sample dispersion of magnetic parameter.Although it is known that Coefficient of variation can express the relative dispersion,but few researchers study on the coefficient of variation,and most of time,they use the standard deviation.The author studies the Coefficient of variation of the magnetic parameter on the rock samples,from the contrast with the self-uniformity and inter-uniformity,and finally get the conclusion that coefficient of variation is a suitable coefficient.
