A researcher is collecting survey data from a random sample of nursing students using gender as the stratifying variable. A disproportionate stratified sampling plan is used to ensure an adequate amount of data from male students. What procedure should the researcher use to estimate overall population values?
A. Weighting
B. Stratification
C. Framing
D. Staging
A. Weighting
Rationale: When the strata in a stratified random sampling plan are of greatly unequal size, as in this example because there are more females than male nursing students, disproportionate sampling can be useful for making comparisons across strata. However, the estimates need to be adjusted through weighting to arrive at overall sample values. Stratification is the procedure for dividing a population into subpopulations. Staging and framing are not terms with relevance to disproportionate sampling.
