A web based software for sample selection from the target population has been
developed which implements selection methodology at every stage for stratified
multi-stage random sampling which is common sample selection procedure across
surveys. It provides both equal and unequal probability based random sample
selection methods.
This web based software is useful for social scientists including survey
statisticians for conducting sample surveys. With the advancement in web
technology and availability of enhanced bandwidth, implementing this web
application for sample selection, accessible to all user is a reality.
This software implements standard procedures for selecting sampling units from
fixed population. It is capable of selecting sample up to stratified three stage
sampling designs. The sampling units are selected on the basis of equal or
unequal probabilities at each stages of selection. Equal probability based
selection methods include Simple Random Sampling With Replacement (SRSWR),
Simple Random Sampling Without Replacement (SRSWOR), Systematic Sampling,
Cluster Sampling etc., whereas, unequal probability based selection includes
Probability Proportional to Size With Replacement (PPSWR).
