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.
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.
Things that are kept the same in the experiment?
Controlled variable.
How many variables are tested during an experiment?

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?

What are the differences between field study and lab study?
Lab study - Artificial environment, high degree of control over extraneous variables Field study - Real environment, low degree of control over extraneous variables but the results gain ecological validity

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.
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."
A sentence with the word extraneous?
During the long, boring lecture, most people agreed that much of the information was extraneous.
Is Friday the 13 a psychological phenomenon?
Not to my knowledge, and it won't likely ever be that way. This is simply because there are too many extraneous variables to ever test something like that.
