What is the purpose of a hypothesis in scientific research?

Back

A hypothesis is a testable prediction about the relationship between variables.

How do you identify the independent variable in an experiment?

Back

The independent variable is identified as the factor that is intentionally changed by the researcher.

Front

What is the role of the dependent variable in an experiment?
