On each trial of an experiment, a participant is presented with a constant soft noise that is interrupted 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 25 trials of this experiment. 190, 202, 212, 221, 243, 250, 257, 271, 288, 288, 288, 309, 311, 315, 323, 335, 359, 364, 388, 418, 440, 476, 526, 603, 756 Send data to calculator Frequency 12- 10- 8- 64 4+ 24 0- 150 11 Send data to Excel Answer the questions below. 10 2 300 450 600 Reaction time (in milliseconds) (a) Which measures of central tendency do not exist for this data set?
