Random uncertainty from repeats
Repeated timing measurements in a fieldwork motion sensor log are \(1.36\,\text{s}\), \(1.4\,\text{s}\), and \(1.43\,\text{s}\). Estimate the random uncertainty using half the range. Enter the numerical result and choose the interpretation that matches the physics meaning.
