What is a n independent variable?
an independent variable is a figure usually shown as a letter that is used in the scientific theory. An independent variable is used in a hypothesized experiment in which this variable is unchanged and is used to effect the dependent variable somewhere in the experiment.
What is the difference between an independent variable and a dependant variable?
In an experiment, the independent variable is the variable that can be altered or controlled to produce a change. The result being studied is the dependent variable, which is observed to change as the independent variable is changed.Example : In an experiment testing the effect of caffeine on reaction times, the amount of caffeine consumed is the independent variable and can be varied. The reaction times are the dependent variable, and a correlation (change in times) with the independent (amount given) is the information being sought.There are three kinds of variables. These are:Independent variable: is not affected by any effects in the experimentDependent variable: its reaction does depend on other variablesControlled variable: variable that you can control throughout the entire experimentTo put it simply, the independent variable tries to manipulate the dependent variable in an experiment.The independent variable (manipulated variable) is a variable that is changed by the experimenter. The dependent variable (responding variable) is what you are trying to determine in an experiment. My 6th grade science teacher taught us a poemThe manipulated is what you control the responding variable is your ultimate goal.
What is the difference between dependent and independent variables?
The independent variable is the variable being manipulated in the experiment in order to show the effect on the dependent variable. It is also called the experimental variable.The dependent variable is the variable being observed in the experiment. Changes in the dependent variable as a result of changes in the independent variable are observed, which is the purpose of the experiment. Dependent variable is also called the response variable.
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 dependent variable independent variable and a control group?
The independent variable is the thing you change, the dependent variable is the variable that changes because of the independent variable, it could also be referred to as the effect, and the control group is the constant, the thing that stays the same and the variable that you compare your results to.
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.
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).
In an experiment to determine the effect of different temperatures on the rate at which bananas ripen, what is the manipulated variable and the responding variable?

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 a controlable variable?
A variable which can be controlled by some other variables or some other parameters is known as controlled variable. A controlled variable is something that can be changed by the experimenter. It is also known as the independent variable. It is something that gives a measure by which to gauge everything else by. For example, if you were testing the effectiveness of a plant fertilizer the "control" would be a plant that is given no fertilizer at all. A controlled variable is the variable that stays the same through out the experiment meaning no changes to it.
What is a independent vairable?
The object you are testing in a hypothesisThe Independant or manipulated variable is what 'I' or you are changing....if you are measuring the effect of fertilizer on plant height, the Independant variable is the presence/absence of fertilizer.
What are independent and dependent variables?
The independent variable is also called an experimental variable. It is the variable being manipulated in the experiment in order to show the effect on the dependent variable. The dependent variable is also called the response variable. It is the variable being observed in the experiment. A change in the independent variable is what causes the change (if any) in the dependent variable, which is the purpose of the experiment.

What is a indepentent variable?
An independent variable is the variable which you change in an experiment. you can only have 1 variable that can change in an experiment and more than one independent variable will result in an unfair experiment
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.
