Question
Briefly explain the independent variable and the dependent variable in an experiment. Describe the relationship between them.
Experiments include two types of changeable factors, or variables: independent and dependent. An independent variable is a manipulated, influential, experimental factor. It is a potential cause. The label "independent" is used because this variable can be manipulated independently of other factors to determine its effect. An experiment may include one independent variable or several of them. A dependent variable is a factor that can change in an experiment, in response to changes in the independent variable. As researchers manipulate the independent variable, they measure the dependent variable for any resulting effect.
