what is the definition of an independent variable in chemistry?

An independent variable is the variable you have control over, what you can choose and manipulate. ... A dependent variable is the variable being tested in a scientific experiment. The dependent variable is 'dependent' on the independent variable.

The Dependent and Independent Variables The independent variable is the variable that is controlled and manipulated by the experimenter. ... The dependent variable is the variable that is measured by the experimenter. In our previous example, the scores on the test performance measure would be the dependent variable.

Independent vs Dependent Variable Key Takeaways The independent and dependent variables are the two key variables in a science experiment. The independent variable is the one the experimenter controls. ... If the independent variable changes, then the dependent variable is affected.

The independent variable is the one that is changed/controlled by the scientist. To ensure a fair test, a good experiment has only one independent variable. ... Experiments also have constants or controlled variables. Controlled variables are things that a scientist wants to remain the same throughout the experiment.

An independent variable is a variable that is manipulated to determine the value of a dependent variable. ... a = b/c the independent variables, b and c, determine the value of a.

One is called the dependent variable and the other the independent variable. The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable. Two examples of common independent variables are gender and educational level.

Independent variables are predetermined factors that one controls and/or manipulates in a designed experiment or an observational study. They are design variables that are chosen to incite a response of a dependent variable.

VARIABLES: The independent variable is the different amounts salt that will be added to the water (what is done by the scientist). The dependent variable is the boiling temperature of the water (what is being measured). III: HYPOTHESIS: If salt is added to water then, the boiling temperature is lowered.

An independent variable is the factor that has some influence or impact on the dependent variable.

In an experiment, the independent variable is the variable that is varied or manipulated by the researcher. The dependent variable is the response that is measured.

: a mathematical variable that is independent of the other variables in an expression or function and whose value determines one or more of the values of the other variables.

Statistics. In an experiment, the variable manipulated by an experimenter is called an independent variable. The dependent variable is the event expected to change when the independent variable is manipulated.

There must be an independent variable, which changes throughout the course of an experiment; a dependent variable, which is observed and measured; and a controlled variable, also known as the "constant" variable, which must remain consistent and unchanging throughout the experiment.

The independent variable is "independent" because its variation does not depend on the variation of another variable in the experiment/research project. The independent variable is controlled or changed only by the researcher. This factor is often the research question/hypothesis behind the outcome of the experiment.

An independent variable, sometimes called an experimental or predictor variable, is a variable that is being manipulated in an experiment in order to observe the effect on a dependent variable, sometimes called an outcome variable.

Independent variable: What the scientist changes or what changes on its own. Dependent variable: What is being studied/measured. The independent variable (sometimes known as the manipulated variable) is the variable whose change isn't affected by any other variable in the experiment.

Dependent and Independent Variables An independent variable, sometimes called an experimental or predictor variable, is a variable that is being manipulated in an experiment in order to observe the effect on a dependent variable, sometimes called an outcome variable.
