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: 170, 206, 218, 232, 238, 248, 254, 264, 268, 281, 281, 281, 316, 320, 320, 329, 336, 365, 399, 400, 438, 438, 452, 524, 724, 806 Frequency 12 12+ 10 10+ 8+ 6+ 4+ 2 2+ 1 1 150 300 450 600 750 1000 Reaction time (in milliseconds) Figure 1 Mean Median (a) Which measures of central tendency do not exist for this data set? Choose all that apply. Mode None of these measures Mean (b) Suppose that the measurement 806 (the largest measurement in the data set) were replaced by 1169. Which measures of central tendency would be affected by the change? Choose all that apply. Median Mode None of these measures Mean (c) Suppose that, starting with the original data set, the smallest Median measurement were removed. Which measures of central tendency would be changed from those of the original data set? Choose all that apply. Mode None of these measures Mean is greater (d) The relative values of the mean and median for the original data set are typical of data that have a significant skew to the right. What are the relative values of the mean and median for the original data set? Choose only one. Median is greater Cannot be determined
