In the statistical calculations for this experiment, the standard deviation in the fixed-interval reaction time experiment is usually lower than that of the random-interval reaction time experiment. What does this mean?
A)It means that average random-interval reaction times are typically shorter than average fixed-interval reaction times. B)It means that there is less variability in the data for the fixed interval reaction time trials than in random-interval trials. C)It means that average random-interval reaction times are typically longer than average fixed-interval reaction times. D)It means that there is more variability in the data for the fixed interval reaction time trials than in random-interval trials. E)It does not indicate any particular trend for fixed-interval vs. random-interval reaction time trials.
For the class as a whole, which condition would you expect to display the shortest average reaction time?
A)Random interval, dominant hand B)Fixed interval, dominant hand C)Random interval, non-dominant hand D)Fixed interval, non-dominant hand E)All 4 of the conditions tested showed the same reaction times.
