What is the accuracy of a stopwatch?
Additional Resources
| Type of clock/watch | Use and accuracy |
|---|---|
| Digital stopwatch | Used to measure short time intervals of minutes and seconds to an accuracy of ±0.01 s |
| Analogue stopwatch | Used to measure short time intervals of minutes and seconds to an accuracy of ±0.1s |
What is the error in a stopwatch?
Human error on using stopwatch The average measurement error using manual timing was evaluated to be around -0.04 s when compared to electronic timing, in this case for a running sprint.
What is the uncertainty in the digital stopwatch readout?
The reading uncertainty of the digital stopwatch is ± 0.005 seconds, which is negligible compared to the standard deviation, which we found to be 0.1 seconds. Thus here the uncertainty in each measurement is the standard deviation.
What is more accurate than a stopwatch?
Far more accurate than quartz crystal oscillations are an atomic time clock. With an error of only 1 second in up to 100 million years, atomic clocks are among the most accurate timekeeping devices in history.

What is uncertainty value?
Uncertainty as used here means the range of possible values within which the true value of the measurement lies. For example, the term accuracy is often used to mean the difference between a measured result and the actual or true value.
What is standard uncertainty?
Standard Uncertainty and Relative Standard Uncertainty Definitions. The standard uncertainty u(y) of a measurement result y is the estimated standard deviation of y. The relative standard uncertainty ur(y) of a measurement result y is defined by ur(y) = u(y)/|y|, where y is not equal to 0.
How do you become comfortable with uncertainty?
5 science-backed tips to help you deal with uncertainty
- Acceptance: Embrace uncertainty as an essential part of life. If this comes easily to you, awesome.
- Gratitude: Zoom in on what’s good.
- Intentional Kindness: Reach out and be kind to someone.
- The Bigger Why: Build a bridge of resilience from your sense of meaning.
- Self-Care: Find comfort in daily rituals.
How do you describe uncertainty?
Uncertainty. The lack of certainty, a state of limited knowledge where it is impossible to exactly describe the existing state, a future outcome, or more than one possible outcome. A state of uncertainty where some possible outcomes have an undesired effect or significant loss.
