Table 3 t-tests of correlation between communication effectiveness (speed and accuracy) in the last round of game played with a target image and the kind of code that was elicited at the end of the experiment for that target image

From: When three’s a crowd: how relational structure and social history shape organizational codes in triads

Test performed on set => All codes (N = 1515) Some dyadic or group level code exists (N = 1389 for time, N = 1405 for accuracy) At least one group level code exists (N = 846 for time, N = 853 for accuracy) There is only one group code (N = 641 for time, N = 647 for accuracy)
  Completely divergent labels Some dyadic or group level code exists Difference Dyadic codes only At least one group level code exists Difference There are multiple codes There is only one group code Difference The label is longer than one word The label is a single word Difference
