they are like cheese they are smooth and stuff like that
Scientists change the independent variable but measure the dependent variable; other variables are kept constant.
The three types of variables are: Independent: it is the one that you manipulate Dependent: the one that reacts to the changes in the independent variable and is measured in a experiment Control: all the other factors that could affect the dependent variable but are kept constant through out an experiment
No, they are not.The constant varible is what stays the same and the dependent varible is whats effected by the change (the independent varibles).
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.
These "variables" are called independent variables or constant variables meaning that they are capable of being changed by the experimenter but are intentionally held the same through each individual experiment.
Independent and Dependent Variables
The control, the constant, the independent variable, and the dependent variable.
Scientists change the independent variable but measure the dependent variable; other variables are kept constant.
The three variable in an experiment are independent, dependent, and controlled. The independent is the variable you control, the dependent is the variable that will change according to the independent. The control is kept constant so they do not affect the dependent.
The three types of variables are: Independent: it is the one that you manipulate Dependent: the one that reacts to the changes in the independent variable and is measured in a experiment Control: all the other factors that could affect the dependent variable but are kept constant through out an experiment
Control Variable
Control variables are kept constant throughout an experiment to ensure that any changes in the dependent variable are due to the manipulation of the independent variable. Experimental variables, on the other hand, are the factors that are deliberately changed by the researcher to observe their effect on the dependent variable.
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.
Depends on the experiment - there may be no relationship. Typically proportional, inversly proportional, proportional to the log and similar are given in set experiments at schools. So a staight line going up and straingt line going down or a curve of some sort when drawn as a line graph.
The variables that can be changed in an experiment are called independent variables. These are the factors that the researcher manipulates or controls to observe the effect on the dependent variable, which is the outcome being measured. Other variables, known as control variables, are kept constant to ensure that any observed changes are due to the independent variable.
Constants or control variables are kept constant during an experiment to isolate the effect of the independent variable on the dependent variable. These variables do not change in order to ensure that any observed changes in the dependent variable are due to the manipulation of the independent variable and not influenced by other factors.
It is a variable. The independent (manipulated) variable is the factor that is different between the control and experimental groups. The dependent variable is the difference resulting from the independent variable. The controlled variables are the factors that are not changed in the experiment between the control and experimental groups.
