A cognitive psychologist investigated the reaction times (in milliseconds) of train drivers under two different cabin lighting conditions: Dynamic LED and Static Fluorescent.
The standard deviation of the reaction times for each condition is presented in the table below.
| Dynamic LED | Static Fluorescent |
|---|---|
| 14.2 | 42.8 |
Explain what these standard deviations suggest about the impact of these cabin lighting conditions on the consistency of the train drivers' reaction times.
