The coefficient of variation is commonly used in medical and biological sciences. In this paper, several parametric and non-parametric tests for the equality of coefficients of variation in k populations are reviewed. Simulation studies are conducted to compare the sizes and power of these tests. It

## Summa y Following SEN & GEBI~ (1975) an estimator for the population mean on the current occasion is proposed. It has been shown that the estimator is more efficient than 'mean per unit estimate' for all kind of populations. The eetimatiors suggeated by SEN & GERIG (1976) and SEABM (1964) are ,

Procedures are developed and compared for testing the equality of two dependent kappa statistics in the case of two raters and a dichotomous outcome variable. Such problems may arise when each of a sample of subjects are rated under two distinct settings, and it is of interest to compare the observe
