COLLECTING DATA

Developing a sound, systematic way to collect data is critical to a good evaluation plan. Evaluation findings are less defensible if data collection procedures are not sound.

Common Ways to Collect Data

The following are some common ways to collect data.

  • Survey -- Collecting data through a structured instrument. Surveys can be mailed (surface or electronic), completed on-site, or administered through interviews (face-to-face or telephone). 
  • Case study -- Examining a particular program, group, individual, or site. Case studies rely on multiple sources of data to get a complete picture.
  • Interviews -- Collecting data by talking with and listening to people. Interviews range from those that are tightly structured (as in a survey) to those that are free flowing and conversational.
  • Key Informants -- Getting information, over time, from a community resident who can provide information on how well a program is serving its intended beneficiaries. Key informants might include school teachers, foodservice managers, and local leaders. 
  • Observation -- Getting information by "seeing" and "listening." Observations can be structured or unstructured.
  • Focus Groups -- Asking a group of 6 to 12 people a semi-structured series of questions. Participants are free to talk with other group members and the focus group moderator. 
  • Delphi -- Getting information from participants without physically assembling them. Information is often exchanged via mail, FAX, or email. 
  • Community Forums -- Sharing ideas at an event that anyone can attend, where a panel of experts shares information, and where members of the audience can ask questions during a pre-set time.
  • Testimonial -- Getting a statement that represents an individual's personal response and/or reaction to an issue or program.
  • Test -- Using established standards to assess knowledge, skills, or performance, such as a certification exam.
  • Photograph, slide, and video -- Using photography to capture visual images.
  • Diary and journal -- Recording events over time to reveal the personal perspective of the writer/recorder.
  • Log -- Recording chronological entries, which are usually brief and factual.
  • Document analysis -- Using content analysis and other techniques to analyze and summarize printed material and existing documents.
  • Action cards -- Using index cards on which participants record what they did (the action) and when they reached their goal.
  • Simulation -- Using models or mock-ups to solicit perceptions and reactions. 
  • Problem story -- Using a narrative account of past, present, or future situations as a means of identifying perceptions. Using fictional characters externalizes the problem situation.
  • Creative expression -- Using art forms to represent people's ideas and feelings through stories, drama, dance, music, or art.
  • Unobtrusive measures -- Gathering information without one knowing. For example, observing food handling practices in a restaurant while eating in the restaurant.
