  RELATIVE PRECISION OF STRATIFIED RANDOM SAMPLING WITH SIMPLE RANDOM SAMPLING   -Garima Singh   Here we are mainly focusing on a comparative study of SRSWOR & Stratified Random Sampling under various methods of allocations.   Let’s start with a simple introduction.   What is sampling? For the purpose of determining population characteristics, instead of enumerating entire population, we take a finite subset of statistical individuals from the population called a sample and this process through which the required number of units are selected is called sampling.   What is Simple Random Sampling (SRS)? In SRS, we draw a sample in such a way that each unit of the population has an equal & independent chance of being selected in the sample. It is of two types: 1.     Simple Random Sampling With Replacement (SRSWR) 2.     Simple Random Sampling Without Replacement (SRSWOR)   What is S...
