A company runs a three day workshop on strategies for working effectively in teams. On each day a different strategy is presented. Forty eight employees of the company attend the workshop. At the outset, all 48 are divided into twelve teams of four. The teams remain the same for the entire workshop. Strategies are presented in the morning. In the afternoon, the teams are presented with a series of small tasks, and the number completed successfully using the strategy taught that morning is recorded for each team. The mean number of tasks completed successfully by all teams each day and the standard deviation is computed. The results are given below.
