Which of the following are adjustment factors applied to adjust for differences in probability of selection between cases in a sample?

A) Sampling spreads.
B) Sampling codes.
C) Sampling classifiers.
D) Sampling errors.
E) Sampling weights.

Sampling weights are used to adjust for differences in probability of selection between cases in a sample. A sampling weight is a value assigned to each case in a sample to reflect its probability of selection, so that cases that are less likely to be selected are given greater weight to compensate for their rarity in the sample. This helps to ensure that the sample is representative of the population from which it was drawn. The other choices are not relevant to adjusting for differences in probability of selection between cases in a sample.
