Can extraneous variables be controlled?
no the variables cant be controlled.
Why it is difficult to control extraneous variables in class rooms?
Extraneous variables are any variables other than the independent variable (the experimental variable) that can affect the real-world situation, with multiple uncontrollable variables that can affect the outcome of any experimental manipulation. These include the different personality, intellectual, and motivational qualities of the individual students in the various classes and the nature and quality of their interactions. Added to this is the fact that each class has a different teacher, whose own personal teaching style may influence the outcome. Some of these extraneous variables can be statistically controlled by the use of techniques like analysis of covariance, but this may be of limited value in a small scale intervention.
Why are control variables kept the same?
Control variables are kept the same to eliminate potential confounding factors that could influence the results of an experiment or study. By holding these variables constant, researchers can more accurately isolate the effect of the independent variable on the dependent variable. This enhances the validity and reliability of the findings, allowing for clearer conclusions to be drawn about causal relationships. Ultimately, controlling for extraneous variables helps to ensure that the observed effects are genuinely due to the manipulation of the independent variable.
What are the different variables during an experiment?
categorical variablesquantitative variablesordinal variablesthere are more common ones like...Controlled/constant variable-Variables that do not change at all!Manipulated/independent variable-Variables that change (intentionally) in order to see their effect on another variable.Responding/depending variable-Is measured quantitatively or qualitatively and is affected by the independent variables.Hope this helps.
What is the basic goal of the experimental method?
The basic goal of the experimental method is to establish cause-and-effect relationships by manipulating one or more independent variables and observing the resulting changes in dependent variables. This method allows researchers to control for extraneous factors, ensuring that any observed effects can be attributed to the manipulated variables. By conducting experiments in a systematic and replicable manner, researchers can draw reliable conclusions about the phenomena being studied.
Can extraneous variables be controlled?
no the variables cant be controlled.
What are examples of extraneous variables?

What are the three variables that play an important role in a Practical Investigation?
Independent Variables, Dependent Variables and Extraneous Variables.
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 a variable that interferes with other variables in a study called?
extraneous variable
Masks the true relationship between the independent and dependent variables?
control

What are the possible variables?
Possible variables can include independent variables, which are manipulated in experiments, and dependent variables, which are measured outcomes. Other types include controlled variables, which are kept constant to ensure a fair test, and extraneous variables, which could unintentionally affect results. Additionally, categorical variables represent distinct groups, while continuous variables can take on a range of values. Identifying and managing these variables is crucial for accurate research and analysis.
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.
What is another word for not needed?
extraneous " not pertinent; irrelevant: an extraneous remark; extraneous decoration."
Is A variable that changes outside the control of the participants an independent variable?
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.
A sentence with the word extraneous?
During the long, boring lecture, most people agreed that much of the information was extraneous.
