Question

vocabulary - match each term to its correct description by writing the letter on the line. 1. __ independent variable 2. dependent variable 3. control group 4. experimental group 5. controlled variables/constants 6. quantitative 7. qualitative 8. hypothesis 9. theory 10. __ law a. everything that stays the same between the control group and experimental group b. a prediction that can be tested through an experiment c. the part of the experiment that contains the independent variable because it is what is being tested d. what is different between the control group and experimental group; what is being tested e. a type of experiment in which the data is collected by making measurements f. describes a natural phenomenon. describes what happens. can be represented mathematically g. the outcome of an experiment; the data that is gathered h. the part of the experiment that does not contain the independent variable; used for comparison i. a type of experiment in which the data is collected by making observations j. it can explain the why. explanation supported by scientific facts and evidence. it has been well - tested and supported

Explanation:

1. The independent variable is what is being changed or tested, so it matches D.
2. The dependent variable is the outcome, matching G.
3. The control group is for comparison without the independent - variable, matching H.
4. The experimental group contains the independent variable, matching C.
5. Controlled variables/constants are the same in both groups, matching A.
6. Quantitative data is collected by measurements, matching E.
7. Qualitative data is collected by observations, matching I.
8. A hypothesis is a testable prediction, matching B.
9. A theory is an explanation supported by facts, matching J.
10. A law describes what happens and can be mathematical, matching F.
