In a study to determine whether viewing pictures of poverty-stricken children increases the tendency for people to donate money
to charity, the experimental group sees pictures of poor children before being asked to donate to charity. The control groups sees pictures of random landscapes. In this study, the operational definition of the dependent variable is the 1 .amount that the experimental group chooses to donate
2. gender ratio in the experimental and control groups
3. gender of the children in the pictures shown
4. choice of landscape pictures
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.
