Summary A new two‐phase sampling procedure is suggested in this paper. The information on the ancillary variate in the preliminary sample is used for selecting the units for sub‐sample with unequal probabilities. Unbiased estimators for the population mean and their variance expressions are obtained for sub‐sampling procedures, both with and without replacement.
