Question 6 6. What is a graph of ordered pairs showing a relationship between two sets of data?

Question 7 7. What do we call a straight line that attempts to predict the relationship between two points?

Question 8 8. What do we call two sets of variables that can change and are compared to find relationships?

Question 9 9. A scientist finishes an experiment, and concludes that there is a causal link between the independent variable and the dependent variable. Why might they come to this conclusion?

Question 10 10. A scientist plots data points from an experiment, and notices that the dependent variables and the independent variables in the data set are decreasing together. What kind of correlation have they discovered, and why?

Question 16 16. A scientist is designing an experiment with rats, and designates weight as the dependent variable. Why might this be the case?

Question 17 17. What is the relationship between two sets of variables used to describe or predict information?

Question 18 18. What do we call a prediction where a variable (y) is dependent on a second variable (x) based on the regression equation of a given set of data?

Question 19 19. What is a condition or piece of data in an experiment that can be controlled or changed?
