On each trial of an experiment, a participant is presented with a constant soft noise, which is interrupted at some unpredictable time by a slightly louder sound. The time it takes for the participant to react to the louder sound is recorded. The following list contains the reaction times (in milliseconds) for 26 trials of this experiment. 156, 202, 214, 222, 234, 250, 279, 280, 280, 297, 298, 299, 301, 303, 311, 329, 340, 358, 373, 394, 419, 436, 451, 583, 701, 864
