## Is water a dependent variable?

The dependent variable is usually what scientists measure in an experiment. In this case, the amount of water is the independent variable because that is what you’re changing in the experiment: one seed gets a lot of water and the other seed only gets a little water.

## How do you identify variables in a research study?

A variable in research simply refers to a person, place, thing, or phenomenon that you are trying to measure in some way. The best way to understand the difference between a dependent and independent variable is that the meaning of each is implied by what the words tell us about the variable you are using.

## What is a dependent variable in science definition?

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).

## Is force a dependent variable?

On the other hand, if we consider a situation where the two variables namely force and acceleration of a moving body is taken in to account then acceleration depends upon force and accordingly, acceleration here is the dependent variable and force is the independent variable.

## Why is distance a dependent variable?

Time is the independent variable (since you have no influence over it) and goes on the x-axis. Distance the dependent variable (it depends on how much time has passed) and therefore goes on the y-axis.

## What is the difference between independent variable and dependent variable in research?

The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable. The dependent variable is the variable being tested and measured in an experiment, and is ‘dependent’ on the independent variable.

## What is control variable in your own words?

Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.

## Is distance a 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 is another name for a dependent variable?

Independent variables are also called “regressors,“ “controlled variable,” “manipulated variable,” “explanatory variable,” “exposure variable,” and/or “input variable.” Similarly, dependent variables are also called “response variable,” “regressand,” “measured variable,” “observed variable,” “responding variable,” “ …

## Is money a dependent or independent variable?

The independent variable is the number of boxes of cookies you buy. The dependent variable is the amount of money you spend on the cookies. The independent variable is the amount of money you spend on the cookies.

## What is a 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.
