| Abstract: | The conditional bias has been proposed by Moreno Rebollo et al. (1999) as an influence diagnostic in survey sampling, when
the inference is based on the randomization distribution generated by a random sampling. The conditional bias is a population
parameter. So, from an applied point of view, it must be estimated. In this paper, we propose an estimator of the conditional
bias and we study conditions that guarantee its unbiasedness. The results are applied in a Simple Random Sampling and in a
Proportional Probability Aggregated Size Sampling, when the ratio estimator is used.
