The aim of an experiment is

• the purpose or objective

• changed by the experimenter

• measured by the experimenter

• kept constant by the experimenter

The independent variable of an experiment is

• the purpose or objective

• changed by the experimenter

• measured by the experimenter

• kept constant by the experimenter

The dependent variable of an experiment is
