The Amount of light. 

Answer 2

Answer:

The amount of light is an independent variable.

Step-by-step explanation:

Consider the provided information.

The independent variable is the variable that the experimenter changes or controls to test the dependent variable impacts.

A dependent variable is the variable that depends on the independent variable and that the experimenter is testing and measuring.

For example:

In a study to determine whether how long you practice affects your game, the independent variable is the time you spent on practice while the dependent variable is the affects on your game.

Now consider the provided information.

In an experiment to see if light affected the amount of interaction, one group of students was put in a lighted room for an hour, and another group was put in a room that was totally dark. Cameras recorded the n in each group.

Here, the light is controlled by the experimenter but affect of interaction is dependents on light.

Thus, the amount of light is an independent variable.
