Controlled Experiment :]
A factor that changes in an experiment is called a dependent variable. It is the variable that is being tested.
It would not be a fair test if there were 2 or 3
The dependent variable is the one being tested in an experiment. It is the variable that is measured or observed to determine the effect of changes in the independent variable. The independent variable is manipulated to see its effect on the dependent variable.
A controlled experiment. In a controlled experiment, one variable (independent variable) is changed or manipulated while all other variables are kept constant to observe the effect on the dependent variable. This allows researchers to determine the specific impact of the variable being tested.
a controlled experiment
A controlled experiment is when a researcher manipulates and controls all variables except for the one being tested, known as the independent variable. This helps to isolate and determine the specific effects of the independent variable on the dependent variable.
One. If there is only one variable being tested, when you compare it to the control, you know that was the cause of a change.
if you change more than one variable, you will not know which one has had an effect on the experiment. If the outcome changes when one variable is altered, then the change can only be due to the one variable, by logical deduction.
The variable observed during an experiment is called the dependent variable. It is the one being measured or tested in response to changes in the independent variable.
The factor being tested in an experiment is the independent variable, which is the variable that is manipulated or changed by the researcher. The control variable is a variable that is held constant to prevent it from affecting the outcome of the experiment. The data collected in an experiment is the information or measurements obtained during the study to analyze and draw conclusions.
2nd one
A variable that doesn't change in an experiment is called a constant. Constants are used to ensure that only one variable is being tested for its effect on the outcome of the experiment.
