# Which of the two is dependent variable?

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.

## What's a example of dependent variable?

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.

## Can there be 2 dependent variables?

There may be more than one dependent variable and/or independent variable. This is especially true if you are conducting an experiment with multiple stages or sets of procedures. In these experiments, there may be more than one set of measurements with different variables.

## Which of the two variables is the independent variable?

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 are the types of dependent variables?

Dependent Variables in Psychology.
...
A dependent variable is also called:
• An experimental variable.
• An explained variable.
• A measured variable.
• An outcome variable.
• An output variable.
• A responding variable.
• A regressand (in regression analysis.)
• A response variable.

## What are the 3 types of 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. The independent variable is the one that is changed by the scientist.

## 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 dependent variable meaning?

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.

## How do you know if two variables are independent or dependent?

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 identify the independent and dependent variables?

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. “The IV causes a change in the DV. It is not possible that DV could cause any change in IV.”

## 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.

## What are the 2 variables in a regression analysis?

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".

## Can you have 3 independent variables?

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.

## Is time a dependent 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.

## Is size a dependent variable?

The dependent variable would be the growth in height or mass of the plant. The controlled variables would be the type of plant, the type of fertilizer, the amount of sunlight the plant gets, the size of the pots, etc.

## How can you tell if two things are independent?

Events A and B are independent if the equation P(A∩B) = P(A) · P(B) holds true. You can use the equation to check if events are independent; multiply the probabilities of the two events together to see if they equal the probability of them both happening together.

## How do you find the independence of two variables?

Two events, A and B, are independent if P(A|B) = P(A), or equivalently, if P(A and B) = P(A) P(B). The second statement indicates that if two events, A and B, are independent then the probability of their intersection can be computed by multiplying the probability of each individual event.

## What are dependent random variables?

Two random variables are called "dependent" if the probability of events associated with one variable influence the distribution of probabilities of the other variable, and vice-versa. The word "influence" is somewhat misleading, as causation is not a necessary component of dependence.

## What are the 5 types of variables?

These types are briefly outlined in this section.
• Categorical variables. A categorical variable (also called qualitative variable) refers to a characteristic that can't be quantifiable. ...
• Nominal variables. ...
• Ordinal variables. ...
• Numeric variables. ...
• Continuous variables. ...
• Discrete variables.

## What is control variable?

A control variable is any variable that's held constant in a research study. It's not a variable of interest in the study, but it's controlled because it could influence the outcomes.

## 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. Not dependent; not contingent or depending on something else; free.

## What are 3 control variables?

Controlled variable: the height of the slope, the car, the unit of time e.g. minutes and the length of the slope.

## What is the dependent variable in this experiment Brainly?

Answer. Explanation: The dependent variable is the variable that is being measured or tested in an experiment. 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.

## What is dependent and independent variable in biology?

There are two key variables in every experiment: the independent variable and the dependent variable. Independent variable: What the scientist changes or what changes on its own. Dependent variable: What is being studied/measured.

## Can there be two independent variables and one dependent?

Yeah, it is possible to measure the relationship between an independent and two or more dependent variables. I will suggest Cause and Effect method or casualty, but there's a catch. - both variables have to respect the rules of a casualty which are 1) both variables have to be correlated to each other or associated.
