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 the difference between correlation and experiment?
An experiment is when the researcher manipulates the independent variable and records its effect on the dependent variable whilst maintaining strict control over any extraneous variables. A correlation is a statistical relationship between two or more variables. The researcher makes a change in one of the variables to see what is affected.
What are three examples of real-world variables?
Time, distance, colour.
Non examples of independent and dependent variables?
doesn't have to have a variable of any thing !!!
What are the uses of Composite Function in real life?
a) Define the concept of culture. Also describe the national cultural variables and individual cultural variables with examples.
Can extraneous variables be controlled?
no the variables cant be controlled.
What are the three variables that play an important role in a Practical Investigation?
Independent Variables, Dependent Variables and Extraneous Variables.
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
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.

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.
What is another word for not needed?
extraneous " not pertinent; irrelevant: an extraneous remark; extraneous decoration."
What are the differences between field study and lab study?
Field studies are conducted in real-world settings, while lab studies are conducted in controlled environments. Field studies tend to have more external validity as they reflect real-world conditions, whereas lab studies offer more control over variables. Field studies may be more challenging to control for extraneous factors compared to lab studies.
When do you need to check for extraneous solutions?
You need to check for extraneous solutions when solving equations containing variables in denominators or within radical expressions. These solutions may arise from introducing new roots or excluded values during manipulations, which need to be verified to ensure they are valid in the original equation.
A sentence with the word extraneous?
During the long, boring lecture, most people agreed that much of the information was extraneous.
