Sampling is more efficient than examining the entire population as it saves time, money and resources. However, it may not always be more effective as there is a risk of bias in the selection of the sample. Option A is incorrect as sampling can be used in both homogeneous and heterogeneous populations. Option C is incorrect as effectiveness depends on various factors including the size and representativeness of the sample. Option D is partially correct as sampling may provide more precise information, but the need for precision is not the only factor to consider when deciding whether to use sampling or not.
