Outline the sources of secondary data

Introduction Identification and evaluation of suitable data sources should be completed within the context of the registry purpose and availability of the data of interest. A single registry may have multiple purposes and integrate data from various sources.

Chapter References Marketing information must be timely, organised, useful and in a simple form if it is to ease decision making. It should also be easily manipulated to satisfy the changing and ad hoc requirements of management for information.

There is more to marketing information than marketing research. Indeed, marketing research is a subsystem of the marketing information system. A Marketing Information System MIS is a structure within an organisation designed to gather, process and store data from the organisation's external and internal environment and to disseminate this in the form of information to the organisation's marketing decision makers.

Chapter 2: Secondary Sources Of Information

Chapter Objectives The objectives of this chapter are: Structure Of The Chapter At the outset of the chapter a strong case is made for studying secondary data before engaging in primary research. The potential benefits of beginning any study with secondary data are outlined, including the prospect that in some cases possession of relevant secondary data may obviate the need for primary research to be undertaken at all.

This discussion is followed by an overview of the questions that should be asked when evaluating secondary sources and data in terms of their validity and accuracy.

Thereafter, the principal internal and external sources of secondary data are described.

The final section of this chapter briefly points towards future developments in the storage and retrieval of secondary data. The nature of secondary sources of information Secondary data is data which has been collected by individuals or agencies for purposes other than those of our particular research study.

For example, if a government department has conducted a survey of, say, family food expenditures, then a food manufacturer might use this data in the organisation's evaluations of the total potential market for a new product.

Similarly, statistics prepared by a ministry on agricultural production will prove useful to a whole host of people and organisations, including those marketing agricultural supplies. No marketing research study should be undertaken without a prior search of secondary sources also termed desk research.

There are several grounds for making such a bold statement. Sometimes primary data collection simply is not necessary.

For the same level of research budget a thorough examination of secondary sources can yield a great deal more information than can be had through a primary data collection exercise. This is not always true but where a government or international agency has undertaken a large scale survey, or even a census, this is likely to yield far more accurate results than custom designed and executed surveys when these are based on relatively small sample sizes.

The assembly and analysis of secondary data almost invariably improves the researcher's understanding of the marketing problem, the various lines of inquiry that could or should be followed and the alternative courses of action which might be pursued. Secondary data can be extremely useful both in defining the population and in structuring the sample to be taken.

For instance, government statistics on a country's agriculture will help decide how to stratify a sample and, once sample estimates have been calculated, these can be used to project those estimates to the population.

· To outline some of the main internal and external sources of data available to commercial enterprises, and · To help the reader to recognise the transition, in marketing research, from a dependence upon published sources of secondary data to electronically stored secondary data. Secondary data is different from primary data on the basis of the sources of their collection. The difference between the two is relative – data which is primary at one place become secondary at another place. The strengths and limitations of secondary data. Posted on April 24, one on the strengths and weaknesses of quantitative secondary sources and one for qualitative. This only gives me the stuff I need for the quantitative grid – is there any information for the qualitative grid?

The problems of secondary sources Whilst the benefits of secondary sources are considerable, their shortcomings have to be acknowledged. There is a need to evaluate the quality of both the source of the data and the data itself. The main problems may be categorised as follows: Definitions The researcher has to be careful, when making use of secondary data, of the definitions used by those responsible for its preparation.

Suppose, for example, researchers are interested in rural communities and their average family size. If published statistics are consulted then a check must be done on how terms such as "family size" have been defined.

They may refer only to the nucleus family or include the extended family.Secondary data is different from primary data on the basis of the sources of their collection. The difference between the two is relative – data which is primary at one place become secondary at another place.

Secondary data is the data that have been already collected by and readily available from other sources. Such data are cheaper and more quickly obtainable than the primary data and also may be available when primary data can not be obtained at all.

Introduction

(33 marks) Sociologists have two types of data available to them: information they have self-generated for their own research purposes (primary data), and already existing data that was not specifically created for sociological purposes (secondary data).

Examples of secondary data are research reports, government reports, censuses, weather reports, interviews, the Internet, reference books, organizational reports and accounting documents. Secondary data can be defined as information collected by someone other than the user. The use of secondary data.

Secondary data is the data that have been already collected by and readily available from other sources. Such data are cheaper and more quickly obtainable than the primary data and also may be available when primary data can not be obtained at all.
