Across
- 3. the investigation is repeated by another person, or by using different equipment and the same results are obtained
- 5. An error that causes readings to differ from the true value by a consistent amount each time
- 8. The quantity between readings
- 10. A proposal intended to explain certain facts or observations.
- 11. Marking a scale on a measuring instrument
- 13. the variable of which the value is measured for each and every change in the independent variable.
- 14. This is the smallest change in the quantity being measured.
- 16. A variable that has to be kept constant or at least monitored.
- 17. The interval within which the true value can be expected to lie.
Down
- 1. The variables have values that are labels, eg names of plants or types of material.
- 2. The maximum and minimum values of the independent or dependent variables
- 4. Measurements in which there is very little spread about the mean value
- 6. A measurement is considered this if it is judged to be close to the true value.
- 7. the variable for which values are changed or selected by the investigator.
- 9. A value in a set of results that does not fit the pattern or id very different from the rest.
- 12. The original experimenter repeats the investigation and obtains the same results.
- 14. An error that causes readings to be spread about the true value,
- 15. variables can have values that can be given a magnitude either by counting or by measurement
