Following the implementation of the training conference, employees were given a short survey (posttest) to assess their satisfaction with the conference. The surveys were used to provide feedback and make changes to next year’s conference.

Repeated measurements of a given behavior are taken across time at equally spaced intervals. Taking multiple measurements is essential for understanding how any given behavior unfolds over time, and doing so at equal intervals affords a clear investigation of how the dynamics of that behavior manifest at distinct time scales.
