What kind of study When performing an experiment to control for confounding variables such as gender the subjects are separated by that possible confounding variable?
The study described is a stratified randomization or stratified design. In this approach, subjects are divided into groups based on the confounding variable (in this case, gender) before random assignment to experimental conditions. This method helps ensure that the potential influence of the confounding variable is balanced across the treatment groups, thereby enhancing the validity of the experiment's results. By controlling for gender, researchers can more accurately assess the effects of the independent variable on the dependent variable.
Why is it important to change one variable and keep all the others constant?
Changing one variable while keeping all others constant is crucial in experiments to establish a clear cause-and-effect relationship. This approach isolates the impact of the variable being tested, allowing researchers to determine its specific effects without interference from confounding factors. It enhances the reliability and validity of the results, making it easier to draw accurate conclusions.
How one variable affects another happens in.... what?

Why do experiments need a control and a variable when dealing with human subjects?

What is the term when a variable unaccounted for in an experiment effects the results in experimental psychology?
confounding variable
What is Situation-Relevant Confounding Variable?
A situation-relevant confounding variable is a third variable that is related to both the independent and dependent variables being studied, which can lead to a spurious relationship between them. It is crucial to identify and control for situation-relevant confounding variables in research to ensure that the true relationship between the variables of interest is accurately captured.
What is the confounding variable in behavior before and after an alcohol treatment program?
Drinking
What is the difference between moderating and extraneous variables?
Extraneous variable a.k.a. Confounding vaiable is a variable that affects an independent variable n also afects a dependent variable at d same time confounding relatnship btn the independent and dependent variable. Mediating variable a.k.a. Intervening variable, it is a variable forming a link btn two variables that are causualy conected.

Is testing a confounding variable when evaluating the effectiveness of an alcohol treatment program?
Yes.
What is an example of a confounding variable?
A confounding variable is an extraneous factor that can influence both the independent and dependent variables in a study, potentially skewing the results. For example, in a study examining the relationship between exercise and weight loss, diet could be a confounding variable, as it impacts both the amount of weight lost and the effectiveness of exercise. If not controlled for, diet may lead to incorrect conclusions about the impact of exercise on weight loss.
What is the name of a factor that seems to disappear?
A factor that seems to disappear is often referred to as a "confounding variable." This is a variable that is not of primary interest in a study, but can influence the results if not properly controlled for. Identifying and addressing confounding variables is crucial to ensure the accuracy and validity of research findings.
What is the meaning of confounding in statistics?
In statistics. a confounding variable is one that is not under examination but which is correlated with the independent and dependent variable. Any association (correlation) between these two variables is hidden (confounded) by their correlation with the extraneous variable. A simple example: The proportion of black-and-white TV sets in the UK and the greyness of my hair are negatively correlated. But that is not because the TV sets are becoming colour sets and so my hair is loosing colour, nor the other way around. It is simply that both are correlated with the passage of time. Time is the confounding variable in this example.
What do you call a factor that confuses the result of an experiment?
A factor that confuses the result of an experiment is called a confounding variable. This variable affects the dependent variable and makes it difficult to determine the true effect of the independent variable being studied. Controlling for confounding variables is important in ensuring the validity and reliability of experimental results.
What are extraneous and confounding variables?
Extraneous variables are factors other than the independent variable that can influence the dependent variable, potentially skewing the results of an experiment. Confounding variables are a specific type of extraneous variable that is related to both the independent and dependent variables, making it difficult to determine the true effect of the independent variable on the dependent variable. Both types of variables can threaten the internal validity of a study if not properly controlled.
What is mean by compounding variable?
I think there is confusion between the terms "compounding variable" and "confounding variable". My way of looking at it is that compounding variables describe elements of mathematical functions, only. Confounding variables apply to any research in any domain and are external variables to the research design which might impact on the dependent variable to a lesser or greater extent than the independent variable, which are part of the research design.
