In statistics, a dependent variable is a measurable factor identified as predictably influenced by one or more independent variables : see also data analysis.
Is a dependent variable always measured?
A dependent variable is what you measure in the experiment and what is affected during the experiment . ... In a scientific experiment, you cannot have a dependent variable without an independent variable. Example: You are interested in how stress affects heart rate in humans.
Which variable is measurable independent or dependent?
The dependent variable is the variable being tested and measured in an experiment, and is ‘dependent’ on the independent variable . An example of a dependent variable is depression symptoms, which depends on the independent variable (type of therapy).
What are the measurable variables?
The measurable variable, as the name suggests, is the variable that is measured in an experiment . It is the dependent variable (DV), which depends on changes to the independent variable (IV). Any experiment studies the effects on the DV resulting from changes to the IV.
How are dependent variables measured?
The dependent variable is the variable that is being measured or tested in an experiment .1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores, since that is what is being measured.
Can time be the 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 are examples of independent and dependent variables?
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. You want to compare brands of paper towels, to see which holds the most liquid.
What is the dependent and independent variable on a graph?
The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line) . ... In graphs with only positive values for x and y, the origin is in the lower left corner.
What type of data is the dependent variable?
Dependent Variables. Dependent variables are the measured behaviors of participants . They are dependent because they “depend on” what the participants do. The most obvious example is text entry speed, measured, for example, in words per minute.
Which is another term for dependent variable?
Depending on the context, a dependent variable is sometimes called a “ response variable “, “regressand”, “criterion”, “predicted variable”, “measured variable”, “explained variable”, “experimental variable”, “responding variable”, “outcome variable”, “output variable”, “target” or “label”.
How do you remember independent and dependent variables?
Many people have trouble remembering which is the independent variable and which is the dependent variable. An easy way to remember is to insert the names of the two variables you are using in this sentence in they way that makes the most sense.
How did you identify the independent variable and dependent variable?
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.
How do you identify independent and dependent variables?
An easy way to think of independent and dependent variables is, when you’re conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect.
What is an example of a measurable variable?
Definition of Variable
These variables should be measurable, i.e., they can be counted or subjected to a scale. The next section provides examples of variables related to climate change, academic performance, crime, fish kill, and crop growth . Note that these variables can be measured.
What are 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 are variables give example of measurable variable?
It can be anything represented by a number. For example: pH (measured with litmus paper) , bone density (measured with a special kind of x-ray) or averages of anything (measured by a formula). These types of variables are sometimes formally called quantitative variables, especially in academia.
