Abstract: | Two-phase sampling is a relatively unknown technique which, in military applications, could save money in several areas of measurement. By first classifying the population through the use of an inexpensive method one reduces the number of expensive measurements which would be required if traditional one-phase sampling were used. Two-phase sampling achieves this by better utilizing information gained by classification than does traditional stratified sampling. |
