A researcher conducted an observational study to investigate how commuters react when an automated ticket barrier at a busy train station displays an error message and plays a warning chime. The researcher observed encounters over a five-day period, recording the primary physical reaction of the passenger immediately behind the blocked barrier. The results from the study are shown in the table below.
