what is the difference between control and independent variable?
21782
There are three main types of variables in a scientific experiment: independent variables, which can be controlled or manipulated; dependent variables, which (we hope) are affected by our changes to the independent variables; and control variables, which must be held constant to ensure that we know that it's our ...

Summary: Independent vs Dependent Variable The independent variable is what you change, and the dependent variable is what changes as a result of that. You can also think of the independent variable as the cause and the dependent variable as the effect.

A constant variable does not change. A control variable on the other hand changes, but is intentionally kept constant throughout the experiment so as to show the relationship between dependent and independent variables.

There are two types of variables, namely independent and dependent variables. The distinction is made on the basis of whether the variable determines the other variable or is determined by another variable. The independent variable is those variables whose value does not depend on any other variable.

Remember, an independent variable is the part of the experiment the scientist changes or controls. The dependent variable is the part of the experiment that reacts to the independent variable. ... A constant is the part that doesn't change during the experiment.

An independent variable is a quantity that is directly controlled by the observer or experimenter. The dependent variable, as its name suggests, depends on the independent variable. The dependent variable is often the quantity you want to measure; it the result of the experiment or test.

An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment. The dependent variable is 'dependent' on the independent variable.

Definitions. 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. ... Here the independent variable is the dose and the dependent variable is the frequency/intensity of symptoms.

An independent variable is defines as the variable that is changed or controlled in a scientific experiment. It represents the cause or reason for an outcome. Independent variables are the variables that the experimenter changes to test their dependent variable.

Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.

The only difference between the two groups is that the independent variable is changed in the experimental group. The independent variable is "controlled" or held constant in the control group. ... The purpose of having a control is to rule out other factors which may influence the results of an experiment.

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.

An independent variable is the variable the experimenter controls. Basically, it is the component you choose to change in an experiment. This variable is not dependent on any other variables. For example, in the plant growth experiment, the independent variable is the light color.

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 manipulated variable is the independent variable in an experiment. It's called “manipulated” because it's the one you can change. ... The controlled variable is the one that you keep constant. The responding variable or variables is what happens as a result of the experiment (i.e. it's the output variable).
