个一 Part 5-Measuring Time A) Looking at your drop times, would you expect the individual times or their average to be more accurate? Why? B) Sometimes the highest and lowest values are discarded when calculating the average. What do you think is the advantage of adopting this procedure? Apply this technique to your experiment. Write in Tables 7 and 8 the new averages calculated using the three best trials. How does this affect your results? C) Did you notice any difference in the times you measured using Visual cues versus Auditory cues? If so, can you find an explanation for the differences? D)

    3. Reaction time experiment (L. Cai, T. Li, Nishant, and A. van der Kouwe, 1996) The experiment was run to compare the effects of auditory and visual cues on speed of response of a human subject. A personal computer was used to present a "stimulus" to a subject, and the reaction time required for the subject to press a key was monitored. The subject was warned that the stimulus was forthcoming by means of an auditory or a visual cue....
