Question

Match the terms with the correct descriptions in the context of this scenario.

1. the gallon of water
2. the new formula of refrigerant
3. the original formula of refrigerant
4. both freezers
5. the time required for the water to turn into ice in each freezer
6. the first freezer
7. the second freezer
Option:
a. explanatory variable
b. response variable
c. control group

Answer 1

The terms in the scenario can be matched to their descriptions as follows: gallon of water - control group, new formula of refrigerant - explanatory variable, original formula of refrigerant - response variable, both freezers - control group, time required for the water to turn into ice in each freezer - response variable, first freezer - control group, second freezer - control group.

Step-by-step explanation:

Match the terms with the correct descriptions:

1. The gallon of water - c. control group
2. The new formula of refrigerant - a. explanatory variable
3. The original formula of refrigerant - b. response variable
4. Both freezers - c. control group
5. The time required for the water to turn into ice in each freezer - b. response variable
6. The first freezer - c. control group
7. The second freezer - c. control group

The gallon of water, the original formula of refrigerant, the time required for the water to turn into ice in each freezer, and the second freezer all represent the control group, as they remain constant and are not manipulated in the experiment.

The new formula of refrigerant is the explanatory variable, as it is the factor being manipulated and tested in the experiment.
