Quick Answer: Does The Dependent Variable Stay The Same?

Can the independent and dependent variable be the same?

No.

The value of a dependent variable depends on an independent variable, so a variable cannot be both independent and dependent at the same time.

It must be either the cause or the effect, not both!.

What factors stays the same all throughout your experiment?

The factors that can change value during an experiment or between experiments, such as water temperature, are called variables, while those that stay the same, such as acceleration due to gravity at a certain location, are called constants.

What are 3 types of variables?

An experiment usually has three kinds of variables: independent, dependent, and controlled.

How do you find a constant variable?

The number before an alphabet (variable) is called a constant. Variable : A symbol which takes various numerical values is called a variable. The alphabet after a number (constant) is called a variable. In the formulas d = 2r; 2 is a constant whereas, r and d are variables.

What are 3 control variables?

There are three main variables: independent variable, dependent variable and controlled variables. Example: a car going down different surfaces.

What is control independent variable and dependent?

Independent variable – the variable that is altered during a scientific experiment. Dependent variable – the variable being tested or measured during a scientific experiment. Controlled variable – a variable that is kept the same during a scientific experiment.

What factors will keep constant?

Answer: The factors that can change value during an experiment or between experiments, such as water temperature, are called variables, while those that stay the same, such as acceleration due to gravity at a certain location, are called constants.

What factors should be kept constant?

TL;DR: In a science experiment, the controlled or constant variable is a variable that does not change. For example, in an experiment to test the effect of different lights on plants, other factors that affect plant growth and health, such as soil quality and watering, would need to remain constant.

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.

What type of variable is gender?

There are two types of categorical variable, nominal and ordinal. 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.

Is the independent variable the one that changes?

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 makes a good control variable?

Variables are just values that can change; a good experiment only has two changing variables: the independent variable and dependent variable. … A control variable is another factor in an experiment; it must be held constant.

Do you keep the dependent variable the same?

The number of dependent variables in an experiment varies, but there can be more than one. … So, you should keep all the other variables the same (you control them) so that you can see only the effect of the one variable (the independent variable) that you are trying to test.

What variable do you keep the same?

control variableEssentially, 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.

What is the independent variable in an experiment 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.
