Question

scenario: a cow is given a growth hormone and then compared to another cow that was not given a growth hormone. both cows were weighed at 2 years.

identify the independent and dependent variables.

Explanation:

Identify the experimental scenario

The scenario describes an experiment where one cow is given a growth hormone and compared to another cow that was not given the growth hormone. Both cows are weighed at 2 years of age.

Determine the independent variable

Using the Experimental Variables concept, the independent variable is the factor that is deliberately changed or manipulated by the researcher. Here, the presence or absence of the growth hormone is manipulated. Thus, the independent variable is the administration of growth hormone.

Determine the dependent variable

Using the Experimental Variables concept, the dependent variable is the factor being measured or observed to see how it responds to changes in the independent variable. Here, the researcher measures the weight of the cows at 2 years. Thus, the dependent variable is the weight of the cows.

Answer:

Independent Variable	Dependent Variable
