Part A1. best fit curve 2. law 3. control 4. quantitative 5. qualitative 6. hypothesis 7. direct relationship 8. theory Part Ba. general or nonspecific observation b. educated guessc. when two variables change in the same direction, one remaining larger than the other by the same factord. "measured" observation e. standard, reference data, or experiment f. a presently accepted explanation of how something happens g. a statement that explains what something does under the same conditions h. a curve drawn to average the data's deviations

Explanation:

Part A and B match as under  

1. best fit curve  ⇔ a curve drawn to average the data's deviations

2. law ⇔ a statement that explains what something does under the same conditions  

3. control ⇔ standard, reference data, or experiment⇔

4. quantitative⇔ "measured" observation

5. qualitative⇔ general or nonspecific observation

6. hypothesis⇔   educated guess

7. direct relationship ⇔ when two variables change in the same direction, one remaining larger than the other by the same factor

8. theory ⇔   a presently accepted explanation of how something happen
