Advantages And Disadvantages Of Secondary Data

Published Date: 02 Nov 2017

The secondary data is nothing but the data collection done by someone other than the user. The secondary data has the common sources for the social science and that includes the records for organization, censuses, and the data collection through the qualitative research or qualitative methodologies. The significance of the government census data are explained below. The statistics of national census and other sources of secondary data are the vital for evaluating the progress of development and comparisons were made as over time and between the countries. The above sources of secondary data were useful for developing studies and the researchers wishes for providing the context for their own field studies of the depth and that had been used by some for making generalizations wider from results of questionnaire surveys in small-scale and focusing the interview researches. Secondary data is used for making an exploration for initial and potential relationships in the arena of development and that will be examined later through the primary fieldwork. It is important to notice that the other secondary data and census will be used as the evidence that is most essential for testing the ideas of the developing studies. The limitation of the government census is subjects for the non-sampling errors.

Advantages And Disadvantages Of Secondary Data

The advantages of secondary data includes the problem can be identified, defining the problem better, developing an approach for the problem, formulating the design for research, answering to certain questions of the research and testing some of the hypotheses and interpreting the primary data. The disadvantages of secondary data includes accuracy and relevance of data were limited, the nature, objectives, and the methods were used for collecting the secondary data and that will not be an appropriate for the current situation and the secondary data were lacking for accuracy, or they are not completely dependable or present. The evaluation of secondary data is explained below. We need to evaluate the secondary data for the reliability and suitability. While evaluating the six criteria will takes place and that includes the purpose of the data to be collected, the data content, methodologies used for collecting the data, when the collection of data has done, data accuracy and the dependability of the overall data. An example for researcher evaluating the secondary data is the discussion on sales data. Sales data were considered as the information that is more valuable for any project of marketing since they are showing the results exactly for a salesperson, program, or sales region. The actual costs will allow the researcher for estimating the costs for the study of research or costs of project for a program of marketing.

Standardized Information

The standardized information is nothing but the type of the secondary data by which the collection of data and the process for collection of data are standardized for the users. the two types of standardized information includes syndicated data and standardized services. The first one is syndicated data. The syndicated data.are the data that can be collected in the format of standard and made available for all the subscribers. The second one is standardized services which is nothing but the research process of standardized marketing and which is used for generating the information for the specific user. The client will be using a standardized service firms for measuring the satisfaction of customer The difference between the two types are given below. The syndicated data aids in the formulation of the decision problem of client and suggesting the types of data for the information needs meeting. An example for the syndicated data are IRI and the Nielsen TV Ratings. The standardized services will rarely provides the client with standardized data, and providing the process of research and helps for reducing cost. An example for standardized services is ESRI’s Community Tapestry. These are about the advantages, disadvantages, difference between the standardised information.

Advantages And Disadvantages Of Standardized Information

The advantages of Syndicated Data includes costs of data that are shared among the users as more clients may be subscribing to the information and that makes the service costs to be reduced, quality of the collection of data which is very high and may require very large amount of cost so it is better to be with the shared cost that will give a reliability and validity of the quality data, data are disseminated more quickly based on the routinized systems. The information will be in the current status and that be in use greatly. The disadvantages of Syndicated Data are the buyers having the little control over what the information is collected, the firms must often commit to contracts of long-term, no information are strategic. The advantages of Standardized Services includes taking the advantage of experience for research firms that offering to the service, reduced cost and speed of the service research. The disadvantages Standardized Services are the ability for customizing some of the projects that are lost, the company that is provides the standardized service that may do not know the certain industry well. These are about the advantages and disadvantages of the two types of standardized information.

Differences Between Primary And Secondary Data

The differences between primary and secondary data are described below. The primary data will always be original as it was collected by an investigator. Secondary data are data that will lack the originality form. The investigator are making use of the data that are collected by some of the agencies. The suitability of primary data will be more positive since it was collected systematically. Secondary data may not suit or may suit the objects that are under enquiry. Primary data are time consuming and expensive. Secondary data are cheaper relatively. Extra precautions for primary data were not required. Secondary data is used with caution and great care. Primary data will be in the shape of the raw materials. Secondary data were usually in the shape of products for readymade. Personal prejudice is possible in the primary data. Less degree of personal prejudice is possible in the secondary data. The Secondary Data is used in the Research of Marketing. We need to use secondary data since it is less expensive and not a time consuming data. Consider an example, In real world the graphs were related to the population of human or statistics of socioeconomic and approximate for any of the mathematical functions other than linear functions.

A Mixed-Mode Survey

Generally, the researchers will never combine the methods for the collection of data. The mixed mode surveys includes Computer-assisted personal interviewing (CAPI), Audio computer-assisted self-interviewing (audio CASI), Computer-assisted telephone interviewing (CATI) and Web surveys. In the Computer assisted personal interviewing (CAPI) the computer will display questions in the screen and the interviewer will read them for respondent, and then enters the answers for respondent. In the audio CASI, that is audio which is assisted by computer will interview self the respondent will operate the computer and that will display the question in screen and recordings were played for the questions and for respondents, who then enters the answers. In CATI, the assist of computer where interviewed through telephone there includes two approaches such as Interactive voice response (IVR) and Web surveys. In the Interactive voice response (IVR) computer will play the recordings for the questions to their respondents through the telephone, who then responds by using the telephone keypad or speaking aloud their answers. In the Web surveys the administration questions of computer are done in online. For example, with the use of mail the program Current Employment Statistics (CES) collects the data monthly, it also uses the data entry of touchtone (TDE), EDI, CATI, FAX, and the Internet were used. These are about the mixed- mode survey.
