Across
- 1. How close a set of repeated measurements are to one another but not the true value, influenced by the random errors of those measurements.
- 3. An experiment is said to be repeatable if the same person with the same equipment obtains the same result when doing the same experiment a number of times, over a short time period.
- 4. The unpredictable variation in a measurement. These can be reduced by taking many repeated measurements and calculating their mean.
- 8. An experiment is said to be reproducible if different people with different equipment, measuring the same quantity, get a similar result.
- 10. The range of values that could reasonably contain the true value of a measurement, based on the confidence an experimenter has about their result.
Down
- 2. Making a reasonable approximation of a value in order to check a calculation or make a quick comparison to another value.
- 5. How close a measurement is to its true value, influenced by the systematic and random errors of that measurement.
- 6. The smallest interval that a given measuring device can measure.
- 7. A consistent shift in readings causing a deviation from the true value. This shift is due to the equipment or method being used and cannot be reduced by repeated measurements.
- 9. The set of seven basic measures from which all other SI units can be derived.
