Book excerpt: Excerpt from Hogs and Pigs: Final Estimates for 1979-82 Hog and Pig estimates were published on a current basis during l979-82 in quarterly and annual reports. Primary data used in setting the current hog estimates were obtained from producers by probability surveys. Survey samples included all known extremely large producers and a sample of smaller producers. Information was collected by mail, telephone, and personal interviews. Since all operations with hogs were not included in the sample, survey estimates are subject to sampling variability. This variability, as measured by the relative standard error, is about 2 percent at the u.s. Level for the hog inventory. This means that chances are approximately 95 out of loo that a survey estimate will be within 4 percent of the complete coverage value if the same procedures are used to survey all producers. Survey estimates are also subject to non-sampling errors such as omissions, duplications, errors in recording and processing the data, and mistakes in reporting. These problems cannot be measured directly, but are minimized through rigid quality' controls during the data collection process, and a careful review of all reported data for consistency and reasonableness. Lists of hog producers are updated annually in each State prior to sampling. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
