Question

question 15 (1 point) match the term to its description: column a 1. a group in an experiment that is used as a comparison. 2. the group that receives the variable being tested. 3. the variable that is measured or observed. 4. b a variable that stays the same throughout the experiment. 5. the variable that is changed by the scientist. column b a. dependent variable b. constant / controlled variable c. control group d. independent variable e. experimental group

Explanation:

1. A control group in an experiment is used as a baseline for comparison, so 1 matches c.
2. The experimental group is the one that receives the variable being tested, so 2 matches e.
3. The dependent variable is what is measured or observed in an experiment (it depends on the independent variable), so 3 matches a.
4. The independent variable is the one the scientist changes to observe its effect, so 5 matches d. (Note: 4 is already matched to b as given.)

Answer:

1. c. Control Group
2. e. Experimental Group
3. a. Dependent Variable
4. d. Independent Variable
