  1. 3. the maximum and minimum values of the independent or dependent variables
  2. 7. the variable for which values are changed or selected by the investigator
  3. 8. the variable for which the value is measured for each and every change in the independent variable
  4. 11. an error due to poor measurements being made
  5. 12. results that do not match the pattern
  6. 17. a variable that have values that are labels. For example, types of material
  7. 18. a relationship that, when drawn on a line graph, shows a positive linear relationship that crosses through the origin
  8. 19. the likelihood that a hazard will actually cause harm
  9. 21. physical, chemical or biological quantity or characteristic that changes
Down
  1. 1. a variable can have values (called a quantity) that can be given by measurement (for example, mass, volume, temperature, etc.)
  2. 2. an error that causes readings to be a value other than the true value, due to results differing from the true value by a consistent amount each time a measurement is made
  3. 3. the link between the variables that were investigated
  4. 4. a test is one in which only the independent variable has been allowed to affect the dependent variable
  5. 5. a forecast or statement about the way something will happen in the future
  6. 6. a measurement is repeatable if the original experimenter repeats the investigation using the same method and equipment and obtains the same or precise results
  7. 9. suitability of the investigative procedure to answer the question being asked
  8. 10. a variable which may, in addition to the independent variable, affect the outcome of the investigation and therefore has to be kept constant or at least monitored
  9. 13. a measurement is reproducible if the investigation is repeated by another person, using different equipment and the same results are obtained
  10. 14. a measurement is one in which there is very little spread close results are to the true (accurate) value
  11. 15. a measurement close to the true value
  12. 16. a proposal intended to explain certain facts or observations
  13. 20. something that can cause harm
