  • Articles and reports: 12-001-X198000254936
    Description:

    The Department of Supply and Services’ role and procedures are outlined as they relate to those using the services of the Department of Supply and Services and those receiving contracts.

    There are two basic principles which cover all the policies and procedures. These are: i) the equality of opportunity to compete for Government contracts must be afforded to all qualified suppliers; and ii) that fair value for the taxpayers’ dollar must be obtained.

  • Articles and reports: 12-001-X198000254940
    Description:

    This paper provides a summary description of some of the characteristics of the proposals for new surveys submitted to Statistics Canada for review and consultation by other federal government departments. It describes which departments have been involved, gives details of the types of studies proposed and methodologies used, and deals briefly with some of the problems which the review process has uncovered.

    Description:

    A major packaged goods manufacturer details his firm’s assemblage and application of market understanding information, impact information, market tracking, share/volume forecasting and documentation procedure.

  • Articles and reports: 12-001-X198000254941
    Description:

    This paper examines the effects of fertility, mortality and migration on the age profile of the Canadian population, particularly the effect of fluctuating fertility patterns which have occurred since the second World War. The author analyses the impact on social services and the economy as the shifting requirements of the “Baby Boom” cohorts move through their life cycle.

  • Articles and reports: 12-001-X198000254937
    Description:

    This paper discusses some of the changes in market research we should expect in the next decade. Currently, studies are issue oriented: they provide answers to specific questions or marketing issues. The next decade will see research projects with a broader scope: to understand how markets work and why consumers behave as they do. Measurements will be more complex, and multivariate analysis techniques will be used extensively to identify the subtle relationships within the data. Marketing models will be the conceptual framework for these more complex studies. Market analysis identifying consumer responsiveness segments provides a case example of what might be expected from model-based market research studies.

  • Articles and reports: 12-001-X198000254944
    Description:

    Due to the absence of hard data and the lack of standardization with respect to nonresponse terminology and reporting procedures, U.S. commercial survey researchers have been unable to obtain an accurate assessment of the nature and extent of the nonresponse problem. However, the results of two recent studies conducted by the author among leading U.S. based market and public opinion research firms revealed that nonresponse is one of the major problems now confronting the commercial survey research industry. This paper discusses the results of the two studies and their implications.

  • Articles and reports: 12-001-X198000254946
    Description:

    This presentation focuses on the present and future social needs of the public, and tracking these needs by surveys. It is divided into two parts. First, the writer gives some history of the tracking systems. Then, he speaks about the future and his forecasts for the new tracking systems.

    Description:

    Increasing costs without a concomitant increase in research budgets are putting severe strains on research quality. Improvements in technology, however, both in the physical domain and in the conceptual domain are sufficient to maintain research productivity at least at its prior level.

  • Articles and reports: 12-001-X198000254938
    Description:

    This paper identifies the stages in the life-cycle of government policies and programs. For each stage, examples are given of how survey research is presently used and likely trends over the next decade are identified.

  • Articles and reports: 12-001-X198000254939
    Description:

    This document describes the process of commissioning market research at Imperial Oil Limited. It outlines the management processes that precede commissioning and defines the expectations of a typical buyer of research work. It also examines the need to have a satisfactory business relationship between the buyer and the seller, and it provides a list of the attributes most often considered by a company seeking a supplier for a particular research project.

  • Articles and reports: 12-001-X198000254945
    Description:

    The article provides a general overview of the concepts of incomplete data and non-response. It is recognized that non-response is an important indicator of data quality, as it affects the estimators by introducing bias and increasing variance due to a reduction in the effective sample size. The relationship between bias and the non-response rate is less obvious, since it depends on the extent of non-response and on the difference in the various characteristics between respondents and non-respondents.

    The most effective way of dealing with the effects of non-response is to minimize its extent. However, any attempt to control the extent of non-response must be based on a good understanding of its origins. The causes and extent of non-response are fundamentally related to (i) the type of survey, (ii) the data capture methods, and (iii) the sample design. However, given a sample design, the extent of non-response will be influenced by factors such as the type of region and the type of non-response.

    There are several ways to handle incomplete data. Each one, in the end, assigns a value to the missing or incorrect data, unless it is decided to publish “raw” data. The procedure for assigning values is called imputation and such an imputed value presumably describes the characteristic of the non-respondent.

    The article provides a brief philosophical explanation about validation and imputation and their applications in the methodology of the various imputation procedures. These include weighting, replication, hot deck imputation using previous data and substitution by a zero value. The using of imputation compared with the methods used in the Canadian Labour Force Survey (LFS) is also discussed. A decision table is provided indicating the various steps to follow for a particular case of a partially completed LFS questionnaire.

    Description:

    The Reverse Record Check is the main vehicle used to assess the level of undercoverage in the Canadian Census of Population. A sample of persons is selected from sources independent of the current census and extensive tracing operations are undertaken to determine the usual address of each selected person as of Census day. Census records are then checked to determine whether or not each selected person was enumerated. The tracing is by far the most complex, costly and time-consuming operation associated with this study. It involves extensive use of administrative records as well as tracing in the field. This paper describes the various tracing methods used as well as the success obtained from each of them.
