Second, considering the small sample size of surveyed hopitals, our results must not be extrapolated to other areas of the North Kivu province or Democratic Republic of the Congo.
Other constraints included the sometimes small sample sizes of surveys (from which, for example, census data do not suffer) as well as occasional definitional inconsistencies among the selected indicators.
The sample sizes of the various ethnic minorities at different survey points ranged from 224 to 2,400 (Table 1); the sample size of each survey ranged from 21,382 to 31,711, and the total sample size (all surveys) was 149,482.
The sample size of 308 survey employees limited this study's power.
A confirmatory factor analysis of the classical HBM was made with data from the post-intervention survey by using Lisrel 8.70 [ 24], since the sample size of the survey was larger.
A central limitation of this study is the small sample size of our survey from which our estimates were generated for modeling purposes.
The main limitation of this study was the small sample size of the survey and the fact that all respondents were members of the same HMO and utilized the same electronic medical record-keeping system.
"Surveys gather research," Mr. Fleischer said, noting the small size of the survey would preclude it from influencing many voters.
Finally, a major limitation of our study was that the small sample size of the survey respondents limited our ability to detect any but large differences between sub-groups.
The target sample size of the survey in each city was 600 households (200 respondents per study neighborhood).
