What is the difference between an independent variable and dependent variable in an experiment?

What is the difference between an independent variable and dependent variable in an experiment?

The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.

What is the difference between a dependent and an independent variable quizlet?

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. You just studied 2 terms!

What is the difference between independent dependent and extraneous variables?

The dependent variable is the variable a researcher is interested in. An independent variable is a variable believed to affect the dependent variable. Extraneous variables are defined as any variable other than the independent and dependent variable.

What’s the difference between dependent and independent student?

What is the difference between independent and dependent students? If you’re a dependent student, you have to report information from both you and your parents. If you’re an independent student, you only have to report your own information (and your spouse’s, if you’re married).

How to determine which variables are dependent or independent?

Method 1 of 3: Understanding Independent and Dependent Variables. Think of an independent variable as a cause that produces an effect.

  • Method 2 of 3: Identifying Variables in Equations. Use letters to represent variables in word problems.
  • Method 3 of 3: Graphing Independent and Dependent Variables. Create a graph with x and y-axes.

    • Can variables be both dependent and independent?

    Yes, there can be more than one dependent variable. In our example, for instance, the growth rate of the plants might be one dependent variable and the overall height of the plants might be another dependent variable. Both of these variables depend upon the independent variable.

    How do you measure an independent 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. In a simple mathematical equation, for example: a = b/c the independent variables, b and c , determine the value of a .

    What are some examples of independent and dependent variables?

    Here are some other examples of dependent and independent variables in scientific experiments:  A scientist studies the impact of a drug on cancer. The independent variables are the administration of the drug – the dosage and the timing. The dependent variable is the impact the drug has on cancer.
