The most helpful basis in dividing the sample into different strata would be a basis that results in different responses across strata. This will ensure that the strata are distinct from one another and will provide more meaningful and reliable results. A basis that results in like responses across strata would not be helpful as it would not allow for meaningful comparisons. The ease of identification and the use of surrogate indicators may be helpful but should not be the primary consideration. The cost should also not be the primary consideration in determining the basis for dividing the sample into different strata.
