By getting rid of the do the job involved with describing clusters that are not selected, multistage sampling can reduce the big expenditures connected to standard cluster sampling. However, Each individual sample may not be a full consultant of the whole populace.
Collection bias: If the real selection probabilities differ from Individuals assumed in calculating the effects.
