Question

scenario

1. 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.

independent: growth hormone administration
dependent:

Explanation:

Identify the experimental setup

The scenario describes an experiment where one cow receives a growth hormone and another does not. Both cows are weighed at 2 years of age to compare their growth. This involves applying the concept of Experimental Variables.

Determine the independent variable

The independent variable is the factor manipulated by the researcher. Here, it is whether or not the cow receives the growth hormone, which is correctly identified in the table as "Growth hormone administration".

Determine the dependent variable

The dependent variable is the factor being measured or observed to see how it responds to changes in the independent variable. In this experiment, the researcher measures the weight of the cows at 2 years of age to see the effect of the hormone. Therefore, the dependent variable is the weight of the cows.
