Non-Probabilistic Sampling Methods â€¢ 3. Mixed Sampling Methods (1) Probability Sampling Methods In this method there is a fixed/ pre-assigned Probability for each member to be selected in the sample from the population. (a) Simple Random Sampling(SRS): In this method there is an equal chance/probability for every member being selected in the sample.

Mixed Sampling Methods (1) Probability Sampling Methods In this method there is a fixed/ pre-assigned Probability for each member to be selected in the sample from the population. (a) Simple Random Sampling(SRS): In this method there is an equal chance/probability for every member being selected in the sample. There are two methods in Simple Random Sampling- One Simple Random Sampling With replacement (SRSWR)& another is Simple Random Sampling without replacement(SRSWOR). Simple Random sampling is useful when- (i) The population size is not very large. (ii) The population under study is not heterogeneous.
