Cause.

The IV is what the experimenter changes, the DV is the result.

Is cause the independent variable?

Not necessarily. The independent variable may have no effect at all.


What shows the relationship between the independent and dependent variable?

Cause and effect


Can a quantitative study have an independent and dependent variables?

Yes. The presumed cause is the independent variable and the presumed effect is the dependent varibale. Variablility in the dependent variable is presumed to depend on variablility in the independent variables. It is used more of a direction of influence rather than a cause and effect scenario. Ex. need for increased assistance is dependent on decrease in health. Health is the independent variable and assistance is the dependent.


Does the independent variable really change independently of the other variable?

The relationship is a matter of cause and effect. An independent variable is given as one upon which another variable depends. So, for example, if you heat a metal pipe, the pipe expands. The amount of expansion is dependent upon the amount of heating that occurs, so expansion is the dependent variable, and the heating, which you may or may not control, is the independent variable. All it means is that if the independent variable ungoes a change, there is an associated and predictable change in the dependent variable. The two are linked inextricably, but one is cause, the other is effect, or to put it another way, you control the change in the dependent variable with input into the independent variable, but it doesn't normally work the other way around.


What does independent variable and dependent variable mean?

The independent variable is the variable that the scientist controls and can change in an experiment. There should be only one independent variable in an experiment; otherwise the cause-and-effect of the independent variable cannot be determined.The dependent variable is the variable that is affected by the independent variable.EXAMPLE:Students of the same age have been given different sleeping hours (the independent variable)The next day they are tested for their performance (the dependent variable).(Having students the same age is a third type of variable, called the constant variable or the control variable. It is deliberately kept the same to reduce any effects on the outcome.)

What is a variable that is used is a independent variable?

An independent variable is the variable of the experiment that the dependent variable depends on. For example, in an experiment testing the effects of soil quality on a plant's growth, the dependent variable would be the plant's growth and the independent variable would be the quality of the soil.


What variable is unchanging?

In an experiment, your control variable will not be caused to vary by the experiment. Think of 'cause and effect'. The independent variable is the cause, the result is the effect, and the dependent variable is the one that you leave to be changed by the experiment.

What is Unchanging?

In an experiment, your control variable will not be caused to vary by the experiment. Think of 'cause and effect'. The independent variable is the cause, the result is the effect, and the dependent variable is the one that you leave to be changed by the experiment.


How does the manipulation of an independent variable during a scientific experiment allow a scientist to find a cause-and-effect relationship between variables?

The independent variable, or manipulating variable always affect the outcome of a dependent, or responsive, variable. For example, i have a fire going, and i want to put it out. I could use a range of materials. The range of materials is the independent variable, while the fire going out or not is the dependent variable. This shows a cause and effect.


What are the main parts of of a controlled experiment?

The main parts of a controlled experiment are the dependent variable and the independent variable. The dependent variable is what is measured in the experiment. The independent variable is the variable that is varied or manipulated by the researcher. The independent variable is the presumed cause, whereas the dependent variable is the presumed effect.


What is an Dependent varible?

Variables used in an experiment or modelling can be divided into three types: "dependent variable", "independent variable", or other.The "dependent variable" represents the output or effect, or is tested to see if it is the effect.The "independent variables" represent the inputs or causes, or are tested to see if they are the cause. Other variables may also be observed for various reasons.


Is customer satisfaction is a dependent variable?

Well, that depends on whether 'customer satisfaction' is the cause or the effect in your analysis. If say, 'prompt attention to customer problems' were the causative (independent) variable, then the 'customer satisfaction' would be the result/outcome/dependent variable. However you could have had a study in which 'customer satisfaction' was the cause/independently variable, and 'likelihood of repeat business' were the result/outcome/dependent variable. You must distinguish between CAUSE and EFFECT. Cause is the independent variable that creates the Effect observed.


How does the manipulation of an independent variable during a scientific experiment allow a scientist to find a cause-and-effect relationship between variable?

The manipulation of an independent variable during a scientific experiment allows a scientist to find a cause and effect relationship between variables. This is because the manipulation changes the results and measurements.


A variable that changes as a result of the other variable?

The dependent variable.


The factor being measure in an experiment?

The dependent variable is monitored as the independent variable is changed. One is testing the effect of the independent variable on the dependent variable (ie effect of dissolved HClO on pH).
