Meaning Of Confounding Variable. When conducting an experiment the basic question that any experimenter is asking is. The amount of association above and beyond that which can be explained by confounding factors provides a more appropriate estimate of the true association which is due to the exposure. Confounding variables share a close relationship with the dependent and independent variables of any research study. A Confounder is an extraneous variable whose presence affects the variables being studied so that the results do not reflect the actual relationship between the.
A variable that is not included in an experiment yet affects the relationship between the two variables in an experiment. Confounding variables or confounders are often defined as the variables that correlate positively or negatively with both the dependent variable and the independent variable. Confounding variables share a close relationship with the dependent and independent variables of any research study. Confounding is the distortion of the association between an exposure and health outcome by an extraneous third variable called a confounder. A confounding variable is also called a confounder confounding factor or lurking variable. A confounding variable leads to a false association between the independent and dependent variable.
This is a terrible definition full of words and phrases that mean nothing to 99 of the population.
1 It occurs when an investigator tries to determine the effect of an exposure on the occurrence of a disease or other outcome but then actually measures the effect of another factor a confounding variable. This extraneous influence is used to influence the outcome of an experimental design. A confounding variable is also called a confounder confounding factor or lurking variable. As most medical studies attempt to investigate disease etiology and causal. A somewhat formal definition of a confounding variable is an extraneous variable in an experimental design that correlates with both the dependent and independent variables. Confounding variables are those that may compete with the exposure of interest eg treatment in explaining the outcome of a study.
