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.

Standard Deviation

A statistical measure that quantifies the variation or dispersion of a set of data points around their mean average.

Fixed-Interval

In the context of psychological reinforcement, it refers to a schedule where rewards are given after a fixed time period has elapsed, assuming a correct response is made.

Random-Interval

A timing schedule in operant conditioning where reinforcements are given at unpredictable intervals.

Final Answer :
B
Explanation :
A lower standard deviation means that the data points are closer to the mean, indicating less variability in the data. Therefore, option B is the best choice as it correctly explains the meaning of lower standard deviation in fixed-interval compared to random-interval reaction time experiments.
