Abstract :

The present work is an attempt to show that cluster sampling is more efficient than simple random sampling provided the mean square within the clusters is maximum and there is a negative intra–class correlation coefficient between elements within clusters as relative efficiency of cluster sampling increases with increase in mean square within clusters. Different estimators of cluster sampling are applied and their results are compared with simple random sampling using the same sample size. Different computer programmes are developed using R–software. All these functions are run on real data set generated on Apple crop from district Ganderbal of Kashmir valley
