. On each trial of an experiment, a participant is presented with a constant soft noise, which is intermpted 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: 1?3, 202, 21 T, 224, 231, 235, 255, 25?, 264, 265, 255, 28?, 304, 322, 323, 328, 330, 365, 377, 385, 434, 445, 46?. 532, 596, 370.

Which measures of central tendency would be affected by the change? Choose all that apply. 1. Mean 2. Median 3. Mode 4. None of these measures (c) Suppose that, starting with the original data set, the smallest measurement were removed. Which measures of central tendency would be changed from those of the original data set? Choose all that apply. 1. Mean 2. Median 3. Mode
