Quizplus · Accepted Answer

Variables refer to measured constructs that can vary across different entities in a sample, such as individuals or objects. They are typically numerical or categorical in nature and are used to quantify the characteristics or attributes of these entities. Variables play a crucial role in statistical analysis as they are used to estimate relationships between different parameters and to make predictions about unknown quantities. Therefore, option C is the best choice since it best describes what variables are. Options A, B, and D are incorrect because they are either too narrow or incorrect in their definitions of variables.
