# Which is the dependent variable?

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

1. Identify the main concepts you are interested in studying.
2. Choose a variable to represent each of the concepts.
3. 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:

1. A variable is an attribute that describes a person, place, thing, or idea.
2. 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.
