Question

Discuss the efficiency of cluster sampling in terms of interclass correlation?​

Answer 1

Answer:

Zark- ovich and Krane (1965) have shown that the correlation between two characters in cluster sampling with clusters as sampling units increases with increase in clus- ter size and correlation coefficient between the clusters as units is expected to be larger than correlation coefficient in element sampling.
