Which is the dependent variable? 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 are the 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**.

## How do you identify an independent variable?

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 the dependent variable the one that changes?

Variables are given a special name that only applies to experimental investigations. One is called the **dependent variable** and the other the independent variable. The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable.

## Where do you plot the independent variable?

The independent variable belongs on **the x-axis (horizontal line)** of the graph and the dependent variable belongs on the y-axis (vertical line).

## 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 a variable?

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 are examples of variables in research?

Categorical variables

Type of variable | What does the data represent? | Examples |
---|---|---|

Nominal variables | Groups with no rank or order between them. | Species names Colors Brands |

Ordinal variables | Groups that are ranked in a specific order. | Finishing place in a race Rating scale responses in a survey* |

## How do you manipulate independent variables?

Again, to manipulate an independent variable means **to change its level systematically** so that different groups of participants are exposed to different levels of that variable, or the same group of participants is exposed to different levels at different times.

## How do you identify an independent and dependent clause?

An independent clause is a group of words that contains a subject and verb and **expresses a complete thought**. An independent clause is a sentence. Jim studied in the Sweet Shop for his chemistry quiz. A dependent clause is a group of words that contains a subject and verb but does not express a complete thought.

## How do you operationalize an independent variable?

How to operationalize concepts

- Identify the main concepts you are interested in studying.
- Choose a variable to represent each of the concepts.
- Select indicators for each of your variables.

## What type of variable is gender?

A nominal variable has no intrinsic ordering to its categories. For example, gender is a **categorical variable** having two categories (male and female) with no intrinsic ordering to the categories. An ordinal variable has a clear ordering.

## What is dependent variable in a graph?

Graphing Rules

1. The independent variable is plotted on the abscissa (also called the x-axis or horizontal axis), while the dependent variable is plotted on the ordinate (also called the y-axis or vertical axis). The dependent variable is **the one whose value changes as a result of changes in the independent variable**.

## Is temperature an independent variable?

For example when examining the influence of temperature on photosynthesis, **temperature is the independent variable** because it does not dependent upon photosynthetic rate. … For example, photosynthesis is dependent upon temperature. A change in air temperature will result in a change in photosynthetic production.

## Why is time a dependent variable?

Time is usually viewed as the independent variable for the simple reason that **it doesn’t depend on anything else**. Time simply ticks by at the same rate wherever you are (in non-relativistic context), independent of other variables so it doesn’t make sense to express time as a dependent variable.

## Is height an independent variable?

the average height of adults might give you a graph as shown below. **The independent variable is average height**. The dependent variable is weight. … For example, height might be an independent variable in the context stated above but a dependent variable in a study on the effect of nutrition on growth rates.

## What do you mean by a variable?

A variable is **a quantity that may change within the context of a mathematical problem or experiment**. Typically, we use a single letter to represent a variable. The letters x, y, and z are common generic symbols used for variables.

## How do you identify a variable in statistics?

In statistics, a variable has two defining characteristics:

- A variable is an attribute that describes a person, place, thing, or idea.
- The value of the variable can « vary » from one entity to another.

## How important is variable in research?

The importance of dependent and independent variables is that they **guide the researchers to per sue their studies with maximum curiosity**. … Dependent and independent variables are also important because they determine the cause and effects in research.

## What is variable in research method?

In research, variables are **any characteristics that can take on different values, such as height, age, species, or exam score**. In scientific research, we often want to study the effect of one variable on another one. … Its value is independent of other variables in your study. The dependent variable is the effect.

## What is variable and its types in research?

Variables represents the measurable traits that can change over the course of a scientific experiment. In all there are six basic variable types: **dependent, independent, intervening, moderator, controlled and extraneous variables**.

## What is the independent variable in distance and time?

On a distance time graph, the distance will always be the dependent variable on the y- axis. **Time is the independent variable** and will always be placed on the x-axis.

## Do you manipulate the independent variable?

In many experiments, the independent variable is a construct that **can only be manipulated indirectly**.

## What are levels of independent variable?

If an experiment compares an experimental treatment with a control treatment, then the independent variable (type of treatment) has two levels: **experimental and control**. If an experiment were comparing five types of diets, then the independent variable (type of diet) would have 5 levels.
