Explanation:

amount that the experimental group chooses to donate

A dependent variable is the variable being tested and measured in a scientific experiment. The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded.

In this case the independent variable are:

experimental group sees pictures of poor children before being asked to donate to charity.

The control groups sees pictures of random landscapes

The amount that the experimental group chooses to donate is dependent on the independent variable.
