Stratified sampling is a method of sampling from a population in statistics. When sub-populations vary considerably, it is advantageous to sample each subpopulation (stratum) independently. Stratification is the process of grouping members of the population into relatively homogeneous subgroups before sampling.tratified sampling is a method of sampling from a population in statistics.

Hardening (computing) In computing, hardening is usually the process of securing a system by reducing its surface of vulnerability, which is larger when a system performs more functions; in principle a single-function system is more secure than a multipurpose one.
Perhaps not! Today Iâll go through security hardening techniques in Windows Server 2008 R2. In my experience, production servers are often deployed without consideration for the overall security posture of the system â an oversight that can often lead to serious security issues in the future.
