在研究项目中,术语“变量”是常见的。当规划定量研究计划,定义和识别的关键变量。在任何调查,比常量变量更兴奋。因此,至关重要的新研究人员理解这个短语和原则是指。换句话说,一个变量是会改变和/或有几个值。”甚至书名所暗示的,一个变量是“事情变化。”Weight, stature, anxiety levels, income, body temperature, and other factors may all have a role. Each of these characteristics varies from person to person, as well as having varied values throughout a scale. Religion, money, profession, climate, humidity, language, food, style, and other factors might be economic, physical, or social. Some characteristics, such as gender, family structure, blood type types, and so on, are extremely definite and obvious, whilst others are far more conceptual and hazy. "A variable is a feature that has several values." It's also a sensible arrangement of characteristics. Characteristics or features that define an object are referred to as attributes. For example, if race is a variable, the characteristics are male and female. If residency is the factor, the qualities are urban, semi-urban, and rural. As a result, qualities here indicate a person's residence. It's important for a scientist to understand how different variables in a study are related to one another.
