Criteria Issues Remarks Specifications & methodology Error & Accuracy Currency Objective Nature Dependability Data collection method, response rate, quality & analysis of data, sampling technique & size, questionnaire design, field work. Examine errors in approach, research design, sampling,data collection & analysis, & reporting. Time lag between collection & publication, frequency of updates. Why were the data collected? Definition of key variables, units of measurement, categories used, relationships examined. Expertise, credibility, reputation, & trustworthiness of the source. Data should be reliable, valid, & generalizable to the problem. Assess accuracy by comparing data from different sources. Census data are updated by syndicated firms. The objective determines the relevance of data. Reconfigure the data to increase their usefulness. Data should be obtained from an original source. Table 4.2 Criteria for Evaluating Secondary Data

American Business Information: Here, There, and Everywhere RIP 4.2 American Business Information Inc. markets subsets of its data in a number of forms, including the professional on-line services (LEXIS-NEXIS and DIALOG), the general online services (CompuServe and Microsoft Network), the Internet (look-ups), and on CD-ROM. The underlying database on which all these products are based contains information on 110 million residential listings and 11 million business listings. ABI also assigns credit scores to company listings. The ABI database most business researchers are familiar with are the American Business Directory and the Canadian Business Directory.

The New York Times on the Web: A New Way to Target Consumers RIP 4.3 The New York Times Electronic Media Company offers The New York Times on the Web database information to advertisers in a manner that enables firms to leverage the site’s 2 million registrants. The database contains demographic information, such as age, gender, income, and Zip code, that ties to an e-mail address for each of the members. This new database marketing system can identify and customize user groups, target web messages to specific segments of the population, and adjust the message based on audience reaction. It can also increase targeting opportunities through third-party data or additional information supplied by the user.
. For example, the database enables an automobile firm to emphasize safety to older customers, luxury to affluent ones, and roominess to families. The system is set up so that near real-time data can be received from the web that indicates how well ads are performing relative to age, gender, and income characteristics. Thus, this system allows a firm to maintain up-to-date information on audiences in order to position its products effectively.
