ABSTRACT
The relationship between the precision of the estimated sampling variances and the number of samples was quantitatively established. It revealed that the product of the standard deviation of the estimated samplingvariance and square root of the number of samples was a constant. Monte Carlo simulation technique was employed to verify the equation. Populations with Gaussian,unifohn random and multi-nomial(taking silicon carbide material as an example) distributions were studied with satisfactory results.
