Variables are the things that are changing in an experiment. A variable is considered any factor, trait, or condition that may exist in different quantities, variations or types. An experiment typically has three kinds of variables and they are: independent, dependent, and controlled. ...
[translate] aIn an experiment, the independent variable is the part of the investigation that is changed. 在实验,独立变量是改变调查的部分。[translate]
In an experiment there are two variables; the Independent Variable (IV) and the Dependent Variable (DV). In the most basic sense, you need two variables because as a researcher, you want to be able to examine if something (a drug, a therapy, a teaching technique, whatever) has an ...

In an experiment, if the independent variable is changed, what might also change? A. Dependent variable B. Control variable C. Constant variable 相关知识点: 试题来源: 解析 A。理解科学实验中的变量关系,自变量改变可能导致因变量改变,答案是 A。
In theBandura Bobo Doll experiment, whether the children were exposed to an aggressive adult, or to a passive adult, was the independent variable. This experiment is a prime example of how the concept of experimental variables can become a little complex. Bandura also studied the differences betw...
What is a dependent variable? The dependent variable is the variable measured in an experiment. It depends on the independent variable! What is a control variable? Control variables are variables that must be kept the same in an experiment. ...
