Question:
An experiment was run to compare the effects of auditory and visual cues on speed of the response of a human subject. The variables for this experiment were type of stimuli ? auditory or visual, and elapsed time between the warning that a stimuli was coming and the stimulus ? 5, 10, or 15 sec. This gave a total of 6 treatment combinations, which can be coded as
1=auditory, 5 sec |
4=visual, 5 sec |
2=auditory, 10 sec |
5=visual, 10 sec |
3=auditory, 15 sec |
6=visual, 15 sec |
The results of the study are given in the table below. The response is in seconds. The experimenter decides to use??= 0.10
