Describe the three types of data sources from which evaluators can obtain pertinent data.

Question

What will be an ideal response?

Answer 1

Agency Records: Information contained in the records of organizations that provide services to the population in question can be useful for estimating the extent of a social problem (Hatry, 2015). Some agencies keep excellent records on their clients although others do not. When an agency’s clients include all the persons manifesting the problem in question and records are faithfully kept, the evaluator may not need to search further. Unfortunately, these conditions are rather rare. Surveys and Censuses: When it is necessary to get very accurate information on the extent and distribution of a social problem and there are no existing credible data, the evaluator may need to undertake original research using sample surveys or censuses (complete enumerations). Either of these approaches can require considerable effort and technical skill as well as a substantial commitment of resources. Sample Surveys: Often conventional sample surveys can provide adequate information. Unfortunately, the method for gathering survey data most common in the past, telephone interviews, has become outmoded owing to the growing prevalence of cell phones and their use to screen calls. Currently, the main methods for administering surveys are by mail, face-to-face, or over the Internet with requests for participation sent via email. Mail surveys for community needs assessment can often be conducted by using household lists from utility services, such as water or electrical providers.
