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 25 trials of this experiment. 182, 204, 208, 221, 247, 248, 260, 284, 284, 284, 297, 310, 317, 323, 334, 341, 373, 374, 388, 426, 432, 470, 550, 635, 845 Send data to calculator Frequency 12 10 8 6 4 2 0 150 11 10 2 1 1 l4 300 450 600 750 1000 Reaction time (in milliseconds) (a) For these data, which measures of central tendency take more than one value? Choose all that apply. (b) Suppose that the measurement 182 (the smallest measurement in the data set) were replaced by 71. Which measures of central tendency would be affected by the change? Choose all that apply. (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. Mean Median Mode None of these measures Mean Median Mode None of these measures Mean Median Mode None of these measures (d) Which of the following best describes the distribution of the original data? Choose only one. O Negatively skewed O Positively skewed O Roughly symmetrical
