Day 21: Interviewing and Experiments

Interviews and experiments are examples of authentic data that depend on the researcher personally, first hand. In a survey, the results kind of depend on the population responding to the survey -- Did they do it? Did they finish it? Did they mark on it in ways that invalidate the answers? Did they return it?

With an interview the researcher meets with or emails the expert directly. Either the meeting happens or does not happen. Even in an experiment, either the researcher performed the experiment or did not. The interview provided the researcher with expert information or did not. The experiment proved or disproved cause and effect.

Interviews and experiments are more direct authentic data for information, a one-on-one, so to speak.

One-to-one feedback is valuable as a
direct tool of communication.
