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 is the independent variable in an experiment 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.
Which is the independent variable in this experiment?
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 manipulates or changes , and is assumed to have a direct effect on the dependent variable.
What are some examples of independent and dependent variables?
Independent variable causes an effect on the dependent variable. Example: How long you sleep (independent variable) affects your test score (dependent variable). This makes sense, but: Example: Your test score affects how long you sleep.
What is the independent variable and dependent variable in an experiment?
Independent variables (IV): These are the factors or conditions that you manipulate in an experiment. Your hypothesis is that this variable causes a direct effect on the dependent variable. Dependent variables (DV): These are the factor that you observe or measure.
How do you find the independent variable?
Independent and dependent variables always go on the same places in a graph. This makes it easy for you to quickly see which variable is independent and which is dependent when looking at a graph or chart. The independent variable always goes on the x-axis, or the horizontal axis .
What are the 3 types of variables?
These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled .
What’s the dependent variable in science?
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 manipulate independent variables?
Again, to manipulate an independent variable means to change its level systematically so that different groups of participants are exposed to different levels of that variable, or the same group of participants is exposed to different levels at different times.
How do you identify independent and dependent variables?
You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment , you manipulate the independent variable and measure the outcome in the dependent variable.
What are examples of independent?
The definition of independent is someone or something that is free from the influence or control of another. An example of independent is someone who lives on their own and supports themself . Free from the influence, guidance, or control of another or others; self-reliant.
What is dependent and independent variable in qualitative research?
The independent variable is the variable that is being manipulated, or the one that varies. It is sometimes called the ‘predictor’ or ‘treatment’ variable. The dependent variable is the outcome (or response) variable .
What is a sentence for dependent variable?
Two multiple regression analyses were performed with each contraceptive measure as a dependent variable. The dependent variable here was equal to 1 if the women had ever used a medical method and zero otherwise .
What is the similarities of independent and dependent variable?
These two variables are used alongside each other, and a change in the independent variable will translate to a change in the dependent variable. That is, they are similar in the sense that they change at the same time . These changes may, however, occur in the opposite direction to each other.
Is time an independent variable?
Time is a common independent variable , as it will not be affeced by any dependent environemental inputs. Time can be treated as a controllable constant against which changes in a system can be measured.
