Mean Formula: Check what is mean, its definition and its formula here. Also, get solved examples of calculating mean for grouped and ungrouped data using direct mean formula and assumed mean method.

This paper develops tests of unconditional mean-variance efficiency under weak distributional assumptions using a Generalized Method of Moments framework. These tests are potentially more robust than ...

For estimating the mean of a finite population using information on an auxiliary variable, a class of estimators is defined as a function of the ratio of sample mean to population mean and the ratio ...
