Quick Answer: What Is Dependent And Independent Variable In Research?

Can time be a dependent variable?

Time is always the independent variable.

The other variable is the dependent variable (in our example: time is the independent variable and distance is the dependent variable)..

What is variable in Research example?

Variable Definition in Research For example, an experimenter might compare the effectiveness of four types of fertilizers. In this case, the variable is the ‘type of fertilizers’. A social scientist may examine the possible effect of early marriage on divorce.

What is dependent and independent variable in Research example?

In a study to determine whether how long a student sleeps affects test scores, the independent variable is the length of time spent sleeping while the dependent variable is the test score. The independent variable in your experiment would be the brand of paper towel. …

What is dependent variable and independent variable in research?

The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable. … The dependent variable is the variable being tested and measured in an experiment, and is ‘dependent’ on the independent variable.

What is dependent variable in research?

Definitions. Dependent Variable. The variable that depends on other factors that are measured. These variables are expected to change as a result of an experimental manipulation of the independent variable or variables.

Which is the dependent variable?

The dependent variable is the variable that is being measured or tested in an experiment. … The dependent variable is dubbed dependent because it is thought to depend in some way on the variations of the independent variable.

How do you know if a variable is independent?

You can tell if two random variables are independent by looking at their individual probabilities. If those probabilities don’t change when the events meet, then those variables are independent. Another way of saying this is that if the two variables are correlated, then they are not independent.

Is stress a dependent or independent variable?

Example: You are interested in how stress affects heart rate in humans. Your independent variable would be the stress and the dependent variable would be the heart rate. You can directly manipulate stress levels in your human subjects and measure how those stress levels change heart rate.

How do you identify independent and dependent variables in research?

You can also think of the independent variable as the cause and the dependent variable as the effect. When graphing these variables, the independent variable should go on the x-axis (the horizontal axis), and the dependent variable goes on the y-axis (vertical axis). Constant variables are also important to understand.

How do you find the dependent variable?

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.

Is weight a dependent or independent variable?

Calorie intake is your independent variable and weight is your dependent variable. You can choose the calories given to participants, and you see how that independent variable affects the weights. You may decide to include a control variable of age in your study to see if it affects the outcome.

What are levels of an independent variable?

time to hit brakes) Levels of an Independent Variable. If an experiment compares an experimental treatment with a control treatment, then the independent variable (type of treatment) has two levels: experimental and control.

How do you identify an independent 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.

What are 3 types of variables?

An experiment usually has three kinds of variables: independent, dependent, and controlled.

Is temperature an independent variable?

An independent variable is one that is unaffected by changes in the dependent variable. For example when examining the influence of temperature on photosynthesis, temperature is the independent variable because it does not dependent upon photosynthetic rate.

What is the importance of independent and dependent variables?

Determining cause and effect is one of the most important parts of scientific research. It’s essential to know which is the cause – the independent variable – and which is the effect – the dependent variable.

What is independent variable in biology?

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.

How do you explain independent and dependent variables?

Independent vs Dependent Variables 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.

What is independent variable in Research example?

The independent variable (IV) is the characteristic of a psychology experiment that is manipulated or changed by researchers, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.

What is another name for dependent variable?

The other name for the dependent variable is the Predicted variable(s). The dependent variables are named as such because they are the values that are predicted or assumed by the predictor / independent variables.
