The independent variableis the variable that is controlled and manipulated by the experimenter. For example, in an experiment on the impact of sleep deprivation on test performance, sleep deprivation would be the independent variable. The dependent variable is the variable that is measured by the ex...
During an experiment, the scientist often wants to observe the results of changing one variable. Only one variable is often changed, as it would be difficult to determine what had caused the relevant response if multiple variables were influenced. The variable that is manipulated by the scientist...
In experimental research, variables are the specific characteristics or factors that are manipulated and measured in order to test a hypothesis. These variables are carefully controlled and manipulated in order to observe the effect on the outcome or dependent variable. For example, in a study examin...
An independent variable has a variety of meanings, depending on the discipline using the term. In science, for example, it is the variable that is being manipulated so that the change in another variable, referred to as the dependent variable, can be measured. One of the biggest challenges ...
Independent Variables: These are the individual variables that you believe may have an effect on the dependent variable. They are sometimes called “explanatory variables,”“manipulated variables,” or “controlled variables.” If this is not already clear, it will be after a couple of examples....
What does manipulated variable mean? What variables must be included in a testable hypothesis? What is test validity? What is bioenergetics testing? What is a randomized double-blind placebo controlled study? What is a positive control? What did the oil drop experiment prove?
