How to Identify Independent and Dependent Variables in an Experiment

What are the steps to determine the independent and dependent variables in an experiment?

A) Identify the variable that is deliberately changed and the variable that is observed and measured

Answer:

The correct answer is A) Identify the variable that is deliberately changed and the variable that is observed and measured.

In an experiment, it is essential to distinguish between the independent variable and the dependent variable. The independent variable is the variable that is deliberately changed by the researcher, while the dependent variable is the variable that is observed and measured as a result of changing the independent variable.

For example, if you are conducting an experiment to test how the amount of water affects plant growth, the amount of water would be the independent variable because you are deliberately changing it to see its effect on plant growth. On the other hand, the plant growth would be the dependent variable because it is what you are observing and measuring in response to the changes in the amount of water.

By following these steps and clearly identifying the independent and dependent variables in your experiment, you can ensure that your results are accurate and reliable.
