In a study to determine whether viewing pictures of poverty-stricken children increases the tendency for people to donate money
ss7ja [257]

Answer:

The dependent variable is the amount of money each group chooses to donate.

Explanation:

A simple way to be able to identify the dependent variable from the independent variable is to observe which element of the research is stimulating something to happen and what this "something" is. This is because the independent variable is the one that has the power to influence the occurrence of "something." This "something" is the dependent variable that occurs when it is influenced by the independent variable.

In the case of the above experiment, we can see that researchers want to research whether looking at pictures of poor children is able to influence the amount of money a person would donate to a charity. Thus, we can affirm that the picture of poor children is the independent variable of the experiment, while the amount of money donated by each group is the dependent variable.
