Quizplus · Accepted Answer

A between-subjects variable refers to a characteristic or condition that varies between different individuals or groups of participants in a study. It is also referred to as an independent variable because researchers manipulate or select the levels of this variable and assign participants to different groups based on these levels. For example, in a study comparing the effectiveness of two different treatments for a medical condition, the treatment received would be a between-subjects variable as it is assigned to different participants.
