An extraneous factor is one that is not pertinent or relevant to what is being studied, for instance, in a research experiment. It may, however, have an unwanted impact if naturally present and not controlled or distributed evenly across groups.
Example: You give the same test to two groups. One group was allowed to study, the other was not. The "study vs. no study" variable is what you are most interested in, and you have attempted to control for other variables that would not be considered relevant to your interest is the study versus no study variable. For instance, the gender of the subjects is not something you want to study in this research, so you make sure that both your study and your no-study subject groups are about the same in terms of gender distribution. You would also want to make sure that the two groups had roughly the same experience in terms of room temperature, time of day taking the test, amount of light to see by and so on so that the groups were differently primarily in whether they studied or not, and nothing else.
According to the Merriam Webster Dictionary, some synonyms for the word extraneous are: accidental, adventitious, alien, external, foreign, and supervenient.
extraneous details
Extraneous writing refers to content that is unnecessary or irrelevant to the main topic or purpose of a piece of writing. It often includes off-topic details, filler phrases, or excessive elaboration that can distract readers from the core message. Effective writing should focus on clarity and conciseness, eliminating any extraneous elements that do not contribute to the overall argument or narrative.
When a variable is directly influenced by another variable it is known as a dependent variable. Conversely, a variable that isn't directly affected by another variable is known as a independent variable.

extraneous variable
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.
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.
False: they are called exogenous.
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.
control
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.

The variable that the investigator changes or manipulates during the experiment is called the independent variable. This is the factor that is deliberately altered in order to observe its effect on the dependent variable, which is the outcome being measured.
