A variable
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?
Scientists test hypothesis by setting up an experiment. They choose a independent and a dependent variable and test the experiment.
Was this in the textbook? The answer is a, the X axis
if your referring to the scientific method, scientists test the dependent variable
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.
