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.
How many variables are tested during an experiment?
There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.
What controlled variables in science?
The number of dependent variables in an experiment varies, but there is often more than one. experiments also have controlled variables are quantities that a scientist wants to remain constant, and he must be observe them as carefully as the dependent variables.
What is the controlled variables in an experiment?
Dependent Variable
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.
Why is it important to use a controlled experimentTHIS IS FOR APEX LEARNING?
Scientists use controlled experiments because they allow for precise control of extraneous and independent variables. This allows a cause-and-effect relationship to be established. Controlled experiments also follow a standardized step-by-step procedure.

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
In an experiment what are controlled variables?
Controlled variables are quantities that must remain constant.
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
What is an advantage of an in vitro experiment?
variables and enviornment conditions are controlled
