Extracted text: 11:13 AA www-awn.aleks.com O DESCRIPTIVE STATISTICS Mean, median, and mode: Comparisons 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. 168, 201, 210, 231, 242, 250, 256, 262, 291, 291, 291, 305, 310, 311, 332, 341, 354, 356, 370, 404, 421, 486, 511, 682, 837 Send data to calculator Send data to Excel Frequency 12- 10 10- 6 4 2 2 150 300 450 600 750 1000 Reaction time (in milliseconds) OMean (a) Which measures of central tendency do OMedian not exist for this data set? Choose all that OMode apply. ONone of these measures OMean (b) Suppose that the measurement 168 (the UMean smallest measurement in the data set) were OMedian replaced by 72. Which measures of central tendency would be affected by the change? ORode Choose all that apply. ONone of these measures (c) Suppose that, starting with the original data set, the largest measurement were removed. Which measures of central tendency would be changed from those of the original data set? Choose all that apply. ONone of these measures OMean OMedian OMode (d) The relative values of the mean and median for the original data set are typical of OMean is greater 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. OMedian is greater Ocannot be determined ? Explanation Check 2021 McGraw-H Education.
