# examples of independent and dependent variables in research studies

## What are examples of dependent variables?

It is something that depends on other factors. For example,

**a test score**could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.## 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 independent and dependent research?

In a well-designed experimental study, the independent variable is the only important difference between the experimental (e.g. treatment) and control (e.g. placebo) groups. The dependent variable is the variable being tested and measured in an experiment, and is ‘dependent’ on 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.## How do you remember the difference between independent and dependent variables?

An easy way to remember the difference between independent and dependent variables is to

**insert the two variables into the following sentence in such a way that it makes sense:****What is this?****Changing (independent variable) affects the value of (dependent variable).**## What is the meaning of 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. It is the presumed effect.## When can we consider if a variable is dependent and independent?

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.## Is gender an independent variable?

**Although social class, religion, gender, ethnicity and age are often treated as independent variables**(e.g., factors, forces, structures) and invoked as causal explanations for various outcomes, this paper approaches these constructs in more distinctive, humanly-engaged terms.

## What are the uses of independent variables?

It

**represents the cause or reason for an outcome**. Independent variables are the variables that the experimenter changes to test their dependent variable. A change in the independent variable directly causes a change in the dependent variable. The effect on the dependent variable is measured and recorded.## What is the independent variable called?

Independent variables are also called

**â€śregressors,â€ś â€ścontrolled variable,â€ť â€śmanipulated variable,â€ť â€śexplanatory variable,â€ť â€śexposure variable,â€ť and/or â€śinput variable.â€ť**Similarly, dependent variables are also called â€śresponse variable,â€ť â€śregressand,â€ť â€śmeasured variable,â€ť â€śobserved variable,â€ť â€śresponding variable,â€ť â€ś …## 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.

## How do you identify the independent and dependent variables in a research topic?

Difference between Independent and Dependent Variable

The easiest way to identify which variable in your experiment is the Independent Variable (IV) and which one is the Dependent Variable (DV) is by **putting both the variables in the sentence below in a way that makes sense**. â€śThe IV causes a change in the DV.

## What are the 3 independent variables?

In this sense, some common independent variables are

**time, space, density, mass, fluid flow rate, and previous values of some observed value of interest**(e.g. human population size) to predict future values (the dependent variable).## What is the aim of dependent variable in writing research problem?

The dependent variable is

**the variable a researcher is interested in**. The changes to the dependent variable are what the researcher is trying to measure with all their fancy techniques.## What are the independent and dependent variables 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.

## How many independent and dependent variables are in research?

Every scientific experiment involves

**at least one independent variable and one dependent variable**. Discover the difference between these two types of variables and review several examples of each type.## Is Y dependent or independent?

Scientists like to say that the “independent” variable goes on the x-axis (the bottom, horizontal one) and the

**“dependent” variable goes on the y-axis**(the left side, vertical one).## How many dependent variables are there?

A well-designed experiment normally incorporate one or two independent variables, with every other possible factor eliminated, or controlled. There may be

**more than two**dependent variables in any experiment.## Can a study have two dependent variables?

**Researchers in psychology often include multiple dependent variables in their studies**. The primary reason is that this easily allows them to answer more research questions with minimal additional effort.

## Is the independent and dependent variables are applicable to all quantitative studies?

**The independent and dependent variables are applicable to ALL quantitative studies**. Which type of quantitative research seeks to determine relationship of one characteristic to the other characteristic?

## How many independent variables are there in research?

There are often

**not more than one or two**independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.
