Differences suggested here above can be summarized to age range, sampling frame
, sample size and survey context.
For instance, the excellent WHO Immunization Coverage Cluster Survey Reference Manual (2005) , subsequent WHO technical support manuals for survey sampling, or comparable publications from the United Nations, typically rely on elements of a member state's civic infrastructure from which to create sampling frames
. These methods, developed in academic centers of industrialized nations, usually depend on registries for voting, vital statistics, licensure of drivers and vehicles, enrollments in schools, labor unions and other social organizations, and other resource lists that are commonplace in developed nations.
Specific criteria for evaluation of observer programs are program longevity, sampling frame
and design, and program implementation.
To determine whether the multivariate statistical model would be feasible, three non-parametric statistical tests were conducted on the rural, metropolitan, and central city core sampling frames
. The first statistical test was the Kruskal-Wallis Test (the non-parametric counterpart of the one-way ANOVA test), which was used to test: (1) The average wage, in the 209 urban counties of selected MSAs in 2005 (vs.
Raw occurrences of species at one or more of the 121 points within each of the nine sampling frames
(121 x 9 = 1,089 total points) used to gather data for each study area (April 2009).
One barrier to conducting general population veteran studies is the absence of a sampling frame
that includes contact information from which to identify and recruit potential research participants.
All the rancher needs is a datasheet, clipboard, pencil, yardstick, and homemade sampling frames
of any size, rectangular or circular.
provide valuable comments on sampling frames
to study fecundity, and we agree that the sampling frame
is a major methodologic problem in fecundity studies of all designs.
However, street youth are often not included in national sampling frames
and data on chlamydia prevalence among Canadian street youth are lacking.

Six sampling frames
based on geography and metropolitan areas were used to allow for spatial comparisons of the 7,976 sampled.
Chapter 3 continues with the technical aspects of research design and deals with sampling frames
, accessing respondents, research design choices, research methods, and data recording.
