Back

The dependent variable is the factor that is measured or observed in response to changes in the independent variable.

How does decreasing the temperature of a room affect a battery's lifespan?

Back

Decreasing the temperature is the independent variable that may affect the battery's lifespan, which is the dependent variable.

Front

What is the conclusion phase in the scientific method?

Back

The conclusion phase summarizes the results of the experiment and states whether the hypothesis was supported or not.
