This data set contains estimates of movement length (in inches) of a light in a completely dark room. Eight groups of three individuals provided three estimates for a total of 72 observations. In four of the groups, participants first made estimates alone prior to providing estimates as a group. In the other four groups participants started as groups. Lang and Bliese (forthcoming) used these data to illustrate how variance functions in mixed-effects models (lme) could be used to test whether groups displayed consensus emergence.
