An extraneous variable is an external factor that can influence the outcome of an experiment but is not the primary variable of interest. For example, in a study examining the effect of a new teaching method on student performance, factors like students' prior knowledge, classroom environment, and time of day could serve as extraneous variables. If not controlled, these variables may introduce bias and affect the results, leading to inaccurate conclusions about the teaching method's effectiveness.
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.
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.
A confounding variable is an extraneous factor that can influence both the independent and dependent variables in a study, potentially skewing the results. For example, in a study examining the relationship between exercise and weight loss, diet could be a confounding variable, as it impacts both the amount of weight lost and the effectiveness of exercise. If not controlled for, diet may lead to incorrect conclusions about the impact of exercise on weight loss.
False solutions that result from multiplying both sides of an equation by a variable are known as "extraneous solutions." These occur because multiplying by a variable can introduce solutions that do not satisfy the original equation, especially if the variable can equal zero. It's important to check all potential solutions in the context of the original equation to identify and exclude these extraneous results.
An experimenter wants to prevent variation from extraneous variables, which are factors other than the independent variable that could influence the dependent variable and skew the results. By controlling or randomizing these extraneous factors, the experimenter aims to ensure that any observed effects can be attributed more confidently to the independent variable being tested. This helps to enhance the validity and reliability of the experimental findings.

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.
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.
False: they are called exogenous.
