Which variable of an experiment changes?
the experimental group
What is the variable that is observed and that changes in response to the manipulated variable?
The dependent variable is the observed one. If there is an experimental effect, then the changes you see in this variable depend on what you did to the manipulated variable.
The factor a scientist changes in a controlled experiment is the?
independent or experimental variable.
Why is it necessary to have an independent variable that is changed by the experimenter during an experiment?
The independent variable is changed by the experimenter so that the results can be compared to the control, which does not change. Any differences between the control and experimental group are due to the independent variable. cw: As written, you don't.
What variables in an experiment which must remain the same in order to perform a fair test of the independent variable?
Except for the independent variable, all other variables must remain the same between the experimental and control groups.
A student wishes to test the hypothesis that adding antifreeze to water lowers the freezing point of the water What would be the dependent variable?
The dependent variable would be the freezing point of the solution.
What is a synonym for experimental variable?
Variable
What conditions must be met if you want to have a scientifically valid sample for a study?
You must have a control group, an experimental group, an experimental variable (also called the independent variable), and a response to be measured (also called the dependent variable). The experimental variable is applied only to the experimental group, so that any difference between the control group and experimental group is due only to the experimental variable. Both the control group and experimental group must have the same conditions, except for the experimental variable.
What is the experimental variable for the study of the effects of anxiety on self-esteem be?

What is the experimental variable?
The independent variable is the one variable that you change in your experiment
What type of a variable is an experimental controls?
independent variable
What is experimental Variable?
The independent variable is the one variable that you change in your experiment
What type of variable is an experimental control?
Independent variable
What is the variable that the scientist changes in an experiment?
experimental variable
What type variable is an experimental control?
Independent variable
What is the difference between experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What is the difference between the independent variable and the experimental variable?
the independent variable is changed, and the experimental value measure. So you control the independent variable and change it to measure the results
