Question

In one of your research experiments, you varied the amount of light exposure of rats to determine whether the rats would press a lever more with more light exposure. The dependent variable in this experiment was the __________.

Answer 1

Answer:

intensity with which the rats pressed the lever

Explanation:

In research, there are two main variables which are dependent or independent.

Independent variables are controlled or manipulated by the experimenter and the independent variable in this experiment is the amount of light exposure.

The response or outcome, which is then measured is the dependent variable. In this experiment, the dependent variable is the intensity with which the rats pressed the lever with varying exposure to light.

In summary, the independent variable has a causal effect on the dependent variable so in this experiment the amount of light exposure has a casual effect on whether the rats would press a lever more.
