What variables must be kept constant
the controlled variables are the factors that are kept constant during an experiment. if they are not kept constant then they may affect the outcome of the experiment. the manipulated variable is the factor that is different between the experiment and the control. the responding variable is the variable that is being measured in the experiment.
Scientists change the independent variable but measure the dependent variable; other variables are kept constant.
In order for the results to be valid, the dependent variable can only be affected by the independent variable, so somethings need to be kept CONSTANT. The things that need to be kept constant are called CONTROLLED VARIABLES. Even if controlled variables are affecting the dependent variable(s), which they usually do, keeping them constant will ensure that all trials of an investigation were equally impacted by the controlled variables, therefore allowing one to see the impact of an independent variable on the dependent variable. All in all, a 'constant' in a science experiment should actually be called a 'controlled variable' and the description of such a variable is described in the third point. Hope this clarifies.
The constant is the number; the variable is the letter.
The factor that is kept constant in an experiment is called the controlled variable. It is important to keep this variable constant to accurately measure the effect of the independent variable on the dependent variable.
A variable that is kept constant in an experiment is called a controlled variable. This variable is deliberately kept the same throughout the experiment to ensure that any changes in the dependent variable are due to the changes in the independent variable.
What variables must be kept constant
A variable that is kept constant in an experiment is called a controlled variable. These variables are kept consistent or unchanged to ensure that any observed changes in the dependent variable are due to the manipulation of the independent variable.
The variable that is kept constant in an experiment is called the control variable. It is important to keep this variable consistent so that any changes in the outcome of the experiment can be attributed to the variable being tested.
In an experiment, the variable that is intentionally kept the same or constant is called the controlled variable. This allows researchers to isolate the effect of the independent variable on the dependent variable.
The constant variable is usually the 'X' variable or the variable that stays the same. For example, it may be the 'X' variable or the same number.
All variables except one, the experimental variable, are kept constant in an experiment.
In Table 2.1, the variable that is typically kept constant is referred to as the control variable. This variable is maintained at a consistent level across different experimental conditions to ensure that any changes in the dependent variable can be attributed to the manipulation of the independent variable.
Control Variable
The control variable, also known as the constant variable, does not vary in an experiment. It is kept constant to ensure that any changes observed are the result of the independent variable being tested.
The controlled variable is the variable that is kept constant , meaning not changed, throughout the entire experiment.
