    Confirming and disconfirming cases assist the evaluator in the confirmatory fieldwork stage of an evaluation. After gathering initial data, exploring the data and identifying patterns, the evaluator will start to develop findings. Confirming and disconfirming cases allow the evaluator to further refine and test initial findings. Both types of cases are important, confirming cases to provide deeper insights to preliminary findings and disconfirming cases to test and highlight the boundaries of the findings.

  2. Convenience Sampling

    Evaluation Option

    Convenience sampling selection is based on the ease or "convenience" of gaining access to a sample. Rather than using a random or purposeful approach to sampling, the evaluator simply gathers data from people who are readily available. This form of data collection works for some areas of study, but using these options may result in low credible cases that produce inaccurate data and questionable results.

  3. Volunteer Sampling

    Evaluation Option

    In many research contexts, sampling simply involves asking for volunteers. Although this can be a convenient, quick and inexpensive way of sampling, the problem with basing a study on a group of volunteers is that there is no evidence that this sample is representative of the wider population that the researcher would like to make generalizations about.

    Projective techniques, originally developed for use in psychology, can be used in an evaluation to provide a prompt for interviews.  Photolanguage is a particular type of projective technique where participants select one or two pictures from a set and use them to illustrate their comments about something.  For example, participants in a workshop might be asked to select two pictures - one that represents you at the beginning of this course and one at the end - and then to discuss the pictures and their hopes and fears about the course and its impacts.

  7. World Cafe

    Evaluation Option

    The World Café is a methodology for hosting group dialogue which emphasizes the power of simple conversation in considering relevant questions and themes. The metaphor of a real-life café is used: in a World Café session, participants – of any number - are encouraged to take part in a collaborative conversation within an environment typically modeled after such a café (i.e. a room furnished with small tables, tablecloth, light music, flowers, refreshments, etc).

  9. Project Records

    Evaluation Option

    Documents developed by the project including periodic project reports (monthly, biannual, annual), baseline data, needs assessments, internal and external evaluations, technical advisor input reports, and field reports.

  10. Official Statistics

    Evaluation Option

    Statistics published by government agencies or other public bodies such as international organizations are often useful in evaluations. These include quantitative or qualitative information on all major areas of citizens’ lives such as economic and social development, living conditions, health, education, the environment.
