What does the dependent variable depend on?
Dependent Variable. Dependent Variable: A dependent variable is what you measure in the experiment and what is affected during the experiment. It is called dependent because it “depends” on the independent variable. In a scientific experiment, you cannot have a dependent variable without an independent variable.
What is dependent and independent variable in Research example?
For example, you might want to test whether students who spend more time studying get better exam scores. The variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variable is the cause. The dependent variable is the effect.
What is another name for an independent variable in regression?
The outcome variable is also called the response or dependent variable, and the risk factors and confounders are called the predictors, or explanatory or independent variables. In regression analysis, the dependent variable is denoted “Y” and the independent variables are denoted by “X”.
What’s the opposite 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.
What is independent variable in research?
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 extraneous variable?
In an experiment, an extraneous variable is any variable that you’re not investigating that can potentially affect the outcomes of your research study. If left uncontrolled, extraneous variables can lead to inaccurate conclusions about the relationship between independent and dependent variables.
What are the examples of extraneous variable?
There are four types of extraneous variables:
- Situational Variables. These are aspects of the environment that might affect the participant’s behavior, e.g. noise, temperature, lighting conditions, etc.
- Participant / Person Variable.
- Experimenter / Investigator Effects.
- Demand Characteristics.
Is gender a participant variable?
Participant variables: Participant variables can be defined as the differing individual characteristics that may impact how a participant responds in an experiment. Examples of participant variables include gender, age, ethnicity, socioeconomic status, literacy status, mood, clinical diagnosis etc.
Why is gender an independent variable?
Note that in this context, gender is considered to be a quasi-independent variable because we cannot actually manipulate gender. Nevertheless, the t-test can be applied to examine differences between men and women on various dependent variables.
Is age and gender an independent variable?
Independent variables included in the first step are demographic variables such as age, gender, marital status, and education, and in the next steps are eco- nomic related variables including employment status and self-rated economic condition.
Can participants be an independent variable?
Independent variables are the conditions tested. They are so named because they are under control of the investigator, not the participant; thus, they are “independent” of the participant.
What is the independent and dependent variable in psychology?
The independent variable is the variable that is controlled and manipulated by the experimenter. The dependent variable is the variable that is measured by the experimenter. In our previous example, the scores on the test performance measure would be the dependent variable.
What is the example of quantitative variable?
As discussed in the section on variables in Chapter 1, quantitative variables are variables measured on a numeric scale. Height, weight, response time, subjective rating of pain, temperature, and score on an exam are all examples of quantitative variables.
Is IQ An example of quantitative variable?
Michigan Algebra II Preview 2012 Other examples of continuous quantitative variables are temperature, age, height, weight and time. Other examples of discrete quantitative variables are the number of legs on an animal, number of siblings, ACT scores, IQ scores, and shoe size.
What is the example of qualitative variable?
A qualitative variable, also called a categorical variable, is a variable that isn’t numerical. It describes data that fits into categories. For example: Eye colors (variables include: blue, green, brown, hazel).
What is variable in quantitative research?
Quantitative variables are those variables that are measured in terms of numbers. Some examples of quantitative variables are height, weight, and shoe size. In the study on the effect of diet discussed above, the independent variable was type of supplement: none, strawberry, blueberry, and spinach.
