A variable
If you purposely change the temperature to test a hypothesis, the temperature is called the independent variable. This is the variable that you manipulate to observe its effect on the dependent variable, which is the outcome you measure in the experiment.
True. In a scientific experiment, the manipulated variable, also known as the independent variable, is the one that is intentionally changed or controlled by the researcher to test its effect on the dependent variable. This allows scientists to observe how changes in the manipulated variable influence the outcome of the experiment.
The manipulated variable, also known as the independent variable, is the factor that is intentionally changed or controlled in an experiment to test its effects on the dependent variable. This variable is crucial for establishing a cause-and-effect relationship in the investigation. By systematically altering the manipulated variable, researchers can observe how it influences other variables, helping to validate or refute the hypothesis being tested.
Amber has written the following hypothesis: "If a rock is put under a great deal of pressure, then the minerals in the rock will chemically change." What is the manipulated variable used in an investigation to test this hypothesis?
The one variable that is purposely changed to test a hypothesis is manipulated variable
The one variable that is purposely changed to test a hypothesis is manipulated variable
The independent variable is purposely changed in an experiment to test a hypothesis. This variable is manipulated by the researcher to observe its effect on the dependent variable and determine if there is a cause-and-effect relationship.
manipulated variable!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The variable that is purposely changed to test a hypothesis is called the independent variable. This variable is manipulated or controlled by the researcher to observe its effect on the dependent variable, which is the outcome being measured.
Independent variable : )
This variable is chosen by the research team according to the experiment project.
The variable that is purposely changed during an experiment to test a hypothesis is the independent variable. This variable is manipulated by the researcher to see how it affects the dependent variable, which is the outcome being measured.
the independent variable, as technically it can change independantly of the rest of the experiment.
The independent variable is the one that is purposely changed to test a hypothesis.There are 3 kinds of variables in a scientific experiment: independent, dependent, and controlled.
A variable
The independent variable is the one that is changed by the scientist.Control variables are kept unchanged in an experiment.Dependant variables are those that change as a result of the independent variable being changed.
