Question

complete the sentence. in this experiment, the temperature of the water was ____________. an independent variable a dependent variable

Explanation:

An independent variable is manipulated by the experimenter. A dependent variable changes in response to the independent variable. Without more context, if the experimenter is changing the water - temperature directly, it is an independent variable. If the water - temperature changes as a result of something else being changed in the experiment, it is a dependent variable. But typically, temperature can be set by the experimenter, so it is often an independent variable.

Answer:

an independent variable
