7. the variable that is being measured or tested in an experiment
10. the value of data in the form of counts or numbers where each data-set has an unique numerical values
13. the quality or state of being correct or precise.
14. the description of an observed phenomenon
16. a measurement of force that is equal to the gravitational pull on an object.
18. one in which the subject or a group would not be tested for the dependent variable
19. a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.
