Testing hypotheses often involves designing experiments. Which of the following is the factor that is observed and measured in an experiment? A. control group B. experimental group C. dependent variable D. independent variable

Answer: Dependent variable

Explanation:

The whole experiment depends on both the factors independent variable and dependent variable.

The independent variable can be changed according to the experiment. The change in independent variable affects the result of the experiment.

The factor that is observed during the experiment is known as dependent variable. This changes as we change the independent variable.

Hence, the correct answer is option c

The correct answer is: dependent variable.

There are two main variables in an experiment: the independent and dependent variable.

The experimenter changes the independent variable and that has the influence on dependent variable. So, the effect on the dependent variable is tested (observed and recorded).
