limitations of tabulation in statistics

These would serve as a guide in deciding which tabulations might be prepared for various administrative levels at a desired level of reliability. It has been the general experience that in a well-formulated agricultural census or survey about two-thirds of the total expenditure goes to planning and conducting the field work while one-third is spent on data processing and data dissemination. Cross tabulation can be used to simplify large data sets. To assist in the creation of an appropriate group of these tables, a check-list of commonly used cross-tabulations is shown later in this chapter. Errors, and omission if any are always detected in tabulation. (2001). Statistics are a set of tools for obtaining insight into a psychological phenomenon. Statistics does not study the individual changes 3. It is a systematic approach with well thought-out, scientific methods and procedures. The type of data affects the advantages and disadvantages of tables and graphs, explains the University of Syracuse. 9.31 Classification by purpose of production is intended to show data separately for holdings which do/do not utilize the marketing structure. Similarly, all data classified by use of one specific cross-classification criterion can be shown in one long table, as is done by some countries. Tabulations using this classification would show distribution of land resources and other characteristics of the holding by size, useful as a basis for government policies on agricultural land and land reform programmes. 9.37 A way of condensing the presentation of the tabulation plan is to show separately: 9.38 It is irrelevant whether basic data are shown in the heading and classes relating to classification criteria in the stub of the table, as shown in the dummy table above, or vice versa, although there may be some advantage in space economy and computer programming, to show basic data in the stub and classes for classification criteria in the heading. Cross-tabulations of different holding characteristics by important classification criteria can show the influence of various factors on agricultural production. ), Total area of agricultural land of holding. Logical sources 2. SUBJECT CONTENT Classes for each of the planned classification criteria (e.g., size classes used in Table 9.2). 9.10 Complete enumeration. Hillsborough disaster  The graphical representation of reports is not free from limitations. The only restrictions occur when limiting the number of pages in the census report and when ensuring that the tables do not disclose confidential data of individual holdings. CHAPTER 1 Classification and Tabulation of Data 1.1. In some countries, data processing may be decentralized with provincial offices responsible for data processing and providing the required tables at the provincial level before submission to the central office and preparing any other tabulations required by local authorities. Disadvantages of direct tabulation of administrative data. Another possible classification of holdings is by area of agricultural land. Cross-tabulation is one technique for measuring association and control - ling other variables and is introduced in this chapter. Often these are included in the data for the year of the outcome of the inquiry rather than year of occurrence, especially when there is a long time lapse. The amount of field work will determine the amount of processing and dissemination. If data are collected by complete enumeration, it is theoretically possible to tabulate data for the smallest geographic areas. These tables may include all data collected but with limited cross-tabulations or possibly in different volumes so that the more important data are available very early. Statistics does not reveal the entire story 6. They should assist in testing the computer programs prepared for tabulation by providing a special data set for program validation. Disadvantages of Graphical Representation of Data. 9.8 Data processing is the responsibility of specialized staff and is covered in Chapter 16. Limitation of Tabulation  Tables contain only numerical data. In fact, even rare characteristics of holdings could be presented. 9.27 Furthermore, classification of data by administrative areas should be considered as one of the most important criteria for classification. Expert Answer . The students seek expert advice or help, have multiple benefits to join us. Tabulation and generation of vital statistics for national policy. 9.20 After the items of information to be tabulated have been determined and corresponding questions have been included in the questionnaire, the manner of arrangement and presentation of these data into tables for analysis and publication can be decided. The Data Tabulation Plan provides model tables that set forth the major findings of a survey in a manner that will be useful to policy makers and program managers. If the revision is of the data is significant, an explanation needs to be given so as not to bias the annual data. 9.7 With electronic data processing and sophisticated data users, one can expect many requests for cross-tabulations; consequently, it is necessary that measures be taken to safeguard data confidentiality, particularly when detailed data breakdowns are made available by size groups and/or small geographic or administrative areas. FAO (1995). This may avoid requests for additional information that arise after field work has been completed. 12. Jain and V.K. Aug 6, 2017 - What is Tabulation? Statistical papers, Series M, No. (In this respect, it can be said that with new developments in computer technology, it becomes less and less useful to print a large set of tables, and more and more useful to invest in a system capable of producing tables upon request. Specific usage. Data limitations and transparency. Common men do not understand them properly. It does not deal with individual items: It is clear from the definition given by Prof. Horace Sacrist, “By … The content of this chapter is in line with the tabulation plan proposed in the FAO Programme for the World Census of Agriculture 2000, and represents the plan for dissemina-tion of census results (Chapter 18). Karnataka 1st PUC Statistics Syllabus and Marking Scheme. Rules of tabulation or precautions for tabulation are numbering, heading, abbreviations, ditto marks, clarity and more. INTRODUCTION The word ‘statistics’ has been derived from the Latin word ‘status’. However, forecasting is not a haywire process. Unit I Introduction to Statistics and Some Basic Concepts: Meaning – Origin – Scope of Statistics. Provide Reference Specially completed questionnaires may be constructed to verify all possible cases in as few questionnaires as possible. In particular, detailed tabulations of rare items such as minor crops are to be avoided. This group may assess past census tabulations and select those to be retained. Microcomputer-based data processing: 1990 World Census of Agriculture. In the case of the 1989 Hillsborough disaster in the UK where 96 people died in a stadium crush, although the deaths were registered they were not included in national vital statistics pending the findings of a coronial enquiry. Cross tabulations provide a way of analyzing and comparing the results for one or more variables with the results of another (or others). The kind, size and number of tabulations required may influence selection of software and, at times, even the hardware requirements. Communications between producers and users of statistics should, therefore, be established early in the preparatory stages of the questionnaire. How to Create a Data Table in Statistics?
