what is the difference independent variable and dependent variable?
47616
Variables are given a special name that only applies to experimental investigations. 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.

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.

The dependent variable is the one that depends on the value of some other number. If, say, y = x+3, then the value y can have depends on what the value of x is. Another way to put it is the dependent variable is the output value and the independent variable is the input value.

' A variable is defined as anything that has a quantity or quality that varies. The dependent variable is the variable a researcher is interested in. An independent variable is a variable believed to affect the dependent variable. Confounding variables are defined as interference caused by another variable.

An independent variable is the variable you have control over, what you can choose and manipulate. Example: You are interested in how stress affects heart rate in humans. ... A dependent variable is the variable being tested in a scientific experiment. The dependent variable is 'dependent' on the independent variable.

The dependent variable is the possible outcome of the experiment; the effect. It depends on what happens to other variables in the experiment. The dependent variable is basically the part that you are changing. For example, if you want to know how much light a plant needs to grow, the amount of growth is the dependent.

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.

The independent and dependent variables are the two key variables in a science experiment. ... The dependent variable is the variable that changes in response to the independent variable. The two variables may be related by cause and effect. If the independent variable changes, then the dependent variable is affected.

Roughly speaking, independent variables represent function inputs, while dependent variables represent function outputs. The value of a dependent variable depends on what the input is.

An independent variable is a variable that is manipulated to determine the value of a dependent variable. The dependent variable is what is being measured in an experiment or evaluated in a mathematical equation and the independent variables are the inputs to that measurement.

The idea is that one variable is the effect of another variable or, to say it another way, that one variable precedes and/or causes another. The dependent variable is the variable to be explained (the 'effect”). The independent variable is the variable expected to account for (the “cause” of) the dependent variable.

They are alternatively called these names because of their role in research experiments. Independent variables are the variables that determine how dependent variables vary, i.e. they predict dependent variables. Dependent variables, on the other hand, are the variables being predicted by the independent variables.

Identify the variables Independent variable – the variable that is altered during a scientific experiment. Dependent variable – the variable being tested or measured during a scientific experiment. Controlled variable – a variable that is kept the same during a scientific experiment.

Remember, the values of both variables may change in an experiment and are recorded. The difference is that the value of the independent variable is controlled by the experimenter, while the value of the dependent variable only changes in response to the independent variable.

What is the difference between independent variables and dependent variables in spreadsheets? Independent variables are the values entered into formulas, while dependent variables are the calculations made by formulas. ... Independent variables are usually numbers, while dependent variables are usually text.

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.
