Halaman 2 - ... comparable, completecoverage values. Estimates of the standard errors have been computed from the sample data for selected statistics in this report. They are presented in the form of relative standard errors (the standard errors divided by the estimated values to which they refer). In conjunction with its associated estimate, the relative standard error may be used to define confidence intervals (ranges that would include the comparable, completecoverage value for specified percentages of all...
Halaman 2 - In addition to the sampling errors, the estimates are subject to various response and operational errors: of collection, response, coding, transcription, imputation for nonresponse, etc. These errors of response and operations would also occur if a complete canvass were to be conducted under the same conditions as the survey. Explicit measures of their effects generally are not available. However, it is believed that most of the important...
Halaman 2 - The complete-coverage value would be included in the range: 1. From one standard error below to one standard error above the derived estimate for about two-thirds of all possible samples.
Halaman 2 - Those proportions, therefore, may be interpreted as defining approximate probabilities that the estimates shown would differ from complete coverage results by as much as one, two, or three standard errors, respectively. For example, suppose an estimated total is shown as SO, 000 with an associated relative standard error of 2 percent.
Halaman 2 - An inference that the comparable, complete-survey result would be within the indicated ranges would be correct in approximately the relative frequencies shown. Those proportions, therefore, may be interpreted as defining...
Halaman 2 - ... 3. From three standard errors below to three standard errors above the derived estimate for nearly all samples. An inference that the comparable, complete-survey result would be within the indicated ranges would be correct in approximately the relative frequencies shown.
