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.
Can extraneous variables be controlled?
no the variables cant be controlled.
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.
A variable that changes as a result of the other variable?
The dependent variable.
Variable is the value whose value depends upon the value of the independent variable?
The dependent variable is the variable that depends on the independent variable.
What is a variable that interferes with other variables in a study called?
extraneous variable
What is the variable in which the investigator changes or manipulates during the experiment?
the experimental variable, also called the independent variable
What is the type of variable that a researcher wants to keep from affecting an experiments outcome?
Extraneous 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 an extraneous solution of an equation?
when you solve a questiom, you get an answer. If you chect your answer by substituting the value of the variable in the question and you don't get L.H.S and R.H.S equal then your answer is called extraneous solution.
The variable not related to the purpose of th study but may affect the dependent variable are termed as extraneous variable true or false?
False: they are called exogenous.
Is A variable that changes outside the control of the participants an independent 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.
Masks the true relationship between the independent and dependent variables?
control
In an experiment l is the control variable m is the response variable and n and p are the extraneous factors. The specific units of are referred to as the treatments of the experiment?
The answer is /
In an experiment f is the control variable g is the response variable and h and k are extraneous factors. The specific units of are referred to as the treatments of the experiment.?
F
In an experiment h is the control variable k is the response variable and l and m are extraneous factors. The specific units of are referred to as the treatments of the experiment?
H
What does extraneous variable mean?
extraneous variable can be defined as any variable other than the independent variable that could cause a change in the dependent variable. In our study we might realize that age could play a role in our outcome, as could family history, education of parents or partner, interest in the class topic, or even time of day, preference for the instructor's teaching style or personality. The list, unfortunately, could be quite long and must be dealt with in order to increase the probability of reaching valid and reliable results.
