Variables that may affect the results of an experiment are described by the umbrella term "extraneous variable". extraneous variables that actually affect the result without experimenter knowledge is called a confounding variables
eg. if the experimenter is testing verbal recall performance, hair color is not going to effect the results. hair color is an extraneous variable, but not compound. but whether or not a subject had a good nights sleep can have a huge effect on the ability to remember words. therefore sleep is a compound variable.

No, an independent variable is one that is intentionally manipulated by the researcher to observe its effect on the dependent variable. A variable that changes outside of the participants' control would typically be considered an extraneous variable that could potentially influence the results of the study.

If participants in the experimental group of a drug treatment study are much younger than participants in the control group the age of the research participants is aNo?
Confounding variable.
What does mean level of the independent variable?
The mean level of the independent variable refers to the average value or level of the variable across all participants or cases in a study. It represents the central tendency of the independent variable within the sample.
What are the elements of experiments and what kinds of variables are there?
The elements of experiments include the independent variable (manipulated by the researcher), dependent variable (outcome being measured), control group (not exposed to the independent variable), and experimental group (exposed to the independent variable). Variables can be independent (controlled by the researcher), dependent (measured to see the effect of the independent variable), or extraneous (unintended variables that can affect the results).
What is the difference between control and control group?

What does a valid experiment must include?
A valid experiment must include a control group for comparison, random assignment of participants to groups, manipulation of an independent variable, and measurement of a dependent variable to test the hypothesis.
In science what changes the control or the variable?
the control can not change ever its like a constant and the dependent variable changes according to the independent variable
Independent variable is known as?
The independent variable is the one that you change in an experiment. The dependent variable changes because of the independent variable. You control the independent and observe the dependent.
How does a psychologist use an independent variable in an experiment?
you have to decipher out what exactly it is saying buut... participants that are exposed to the independent variable are in the experimental group and the participants who are treated the same way as the experimental group, except that they are not exposed to the independent variable, make up the control group... any...

What is a dependent variable independent variable and a control group?
The independent variable is the thing you change, the dependent variable is the variable that changes because of the independent variable, it could also be referred to as the effect, and the control group is the constant, the thing that stays the same and the variable that you compare your results to.
Independent vs dependent variables?
Free from outside control means Independent . While dependent Is opposite.
Is a manipulative variable the same as an independent variable?
Yup, a manipulative variable is the variable a scientist deliberately changes. This is also called an independent variable.
What is a control test?
Control Test is the separate experiment that serves as a standard for comparison to identify experimental effects, changes of the dependent variable resulting from changes to the independent variable.
Definitions of the 3 types of variables in doing an experiment?
The three variable in an experiment are independent, dependent, and controlled. The independent is the variable you control, the dependent is the variable that will change according to the independent. The control is kept constant so they do not affect the dependent.
What are the three types of variables?
The three types of variables are: Independent: it is the one that you manipulate Dependent: the one that reacts to the changes in the independent variable and is measured in a experiment Control: all the other factors that could affect the dependent variable but are kept constant through out an experiment
Does the independent or dependent variable change?
The Independent variable is the one you control. The dependent variable is controlled by the Independent Variable.
The variable which is deliberately changed in experiment?
Independent, it is in the name, more variables are: dependant variable- the one you keep the same control variable- mearsuring variable
