A cоnsulting firm cоnducted аn experiment tо аnаlyze how work arrangement and manager support type impact task completion time for a standardized data-reporting task. They used a 3×4 factorial design: Factor A – Work arrangement In-office Hybrid Fully remote Factor B – Manager support type No support Weekly check-ins On-demand assistance (Slack availability) Dedicated mentor during the task A total of 5 employees were randomly assigned to each combination and completed the same task. The response variable was the time it took to finish the task (in minutes). The data is shown below.
