What variables must be kept constant
Constant variable
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.
Such a number is called a "constant". If the number appears in front of a variable, it is sometimes called a "coefficient".
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.
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.
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.
Control Variable
What variables must be kept constant
The variable that is held constant in an experiment is called the controlled variable. This variable is kept consistent to ensure that any changes in the outcome of the experiment are due to the manipulated variable being tested.
In an experiment, variables that must be kept constant are called control variables. Two common examples include temperature and pH levels. These variables should be kept constant to ensure that any changes observed in the dependent variable are a result of the independent variable being tested.
Constant variable
The independent variable. Any variable that is kept the same is a constant variable (although it is a contradiction in terms); any variable - usually only one - that depends on the independent variable is a 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.
