After presenting the main types of survey design, list sample design and area sample design, other important uses of sampling techniques in the statistical work, are also mentioned, such as the application of sampling in quality control of the field and data processing operations, pre-testing of questionnaires, and various statistical operations.
The construction of frames is discussed in Chapter 7. The statistical theory and practice of survey design for agricultural surveys is beyond the scope of this publication, and the reader may consult the list of suggested references on survey methods for agricultural censuses and surveys included at the end of the chapter.
Objectives of agricultural censuses and surveys 6. To provide aggregate totals for fundamental agricultural data for use as the benchmark for inter-censal estimates. To provide a frame for other agricultural sample surveys.
To provide data for small administrative units and detailed cross-classifications of holding structural attributes. The FAO Programme for the World Census of Agriculturefor instance, corresponds to agricultural censuses to be undertaken during the decade Census data are also useful in the design of annual or seasonal agricultural sample surveys.
For example, stratification criteria for current surveys are included in the census questionnaire: Clustering procedures and assignment of probabilities of selection for current agricultural surveys are also often based on agricultural census data.
Sample design and survey design 6. For instance, it can be carried out using a number of different enumeration procedures e. Indeed, in developing countries it is not generally feasible to use, on a large-scale, other data collection procedures, such as self-administered questionnaires, mail, or telephone.
Complete enumeration censuses versus censuses carried out on a sample basis 6. The main characteristics of these two categories are the following: For agricultural censuses conducted by complete enumeration which are called simply agricultural censuses in many countriesthe enumerators complete a questionnaire for each holding.
The result for each characteristic is obtained from the values of the characteristics in all holdings.
Therefore, the census results include only non-sampling errors. Agricultural censuses based on sample enumeration are probability sample surveys, that is, surveys for which a probability sample of sampling units is selected, and for which the methods of estimation for each census characteristic allows establishing their statistical precision.
This requires, in particular, defining the sampling units and their probability of selection, from a known universe frame. Advantages of carrying out a census on the basis of complete enumeration 6.
Such information is sometimes required by law, for local planning, or for practical purposes such as irrigation projects or projects on regionalization or on an agro-climatic and ecological basis.
Sampling methods cannot provide accurate information for small administrative sub-divisions. Information on such crops can only be reliably obtained from a complete census. The situation is similar with regard to rare species of animals, or any other rare variable.
Sampling methods cannot provide accurate information on variables that occur infrequently. These sample surveys can be planned much more efficiently if census results are available for small area units.
First, the census listings can be used as a frame for the selection of the sample.
This may prove an important saving because the preparation of the frame itself generally consumes a significant part of the budget allocation for the sample survey. Furthermore, census data can be used for improved sampling design and better estimation procedures, which may lead to more reliable estimates of the characteristics under study.
This constitutes an important advantage in countries with limited technical expertise. Processing the data from a sample enumeration is technically more complicated.2. A new pill comes on the market. It alters the chemicals in your brain and changes your mood and personality.

Gender is the range of characteristics pertaining to, and differentiating between, masculinity and pfmlures.coming on the context, these characteristics may include biological sex (i.e., the state of being male, female, or an intersex variation), sex-based social structures (i.e., gender roles), or gender identity.
Traditionally, people who identify as men or women or use masculine or. Gender theories Differences in gender roles have existed throughout history.
Evolutionary theorists attribute these differences to the physiological characteristics of men and women that prescribed their best function for survival of the species.
