Down 1. a line that runs up and down along the side of a graph on which the responding variable (dependent variable) is labeled 2. the factor that changes as a result of changes to the manipulated or independent variable; also called a dependent variable 4. the ongoing process of discovery in science; the diverse ways scientists study the natural world and propose explanations based on evidence they gather 7. a line graph in which the data points yield a straight line 9. a statement that describes how to measure a particular variable or a particular term 11. a factor that can change in an experiment 12. a well-stated concept that explains a wide range of observations 13. a pair of numbers used to determine the position of a point on a graph 15. a line graph in which the data points do not fall along a straight line 19. a possible explanation for a set of observations; educated guess 20. the amount of space an object takes up
