In applied statistics, (e.g., applied to the social sciences and psychometrics), common-method variance (CMV) is the spurious "variance that is attributable to the measurement method rather than to the constructs the measures are assumed to represent" or equivalently as "systematic error variance shared among variables measured with and introduced as a function of the same method and/or source". For example, an electronic survey method might influence results for those who might be unfamiliar with an electronic survey interface differently than for those who might be familiar. If measures are affected by CMV or common-method bias, the intercorrelations among them can be inflated or deflated depending upon several factors. Although it is sometimes assumed that CMV affects all variables, evi

rdfs:comment	Der Begriff Methodenverzerrung (engl. common-method bias) bezeichnet in der Empirie eine Verzerrung der Messergebnisse, die dadurch entsteht, dass die Befragten gleichzeitig Quelle für die exogene Variable als auch die endogene Variable sind. Die Befragten können bspw. häufig aus dem Fragebogen Schlussfolgerungen auf die zugrundeliegenden Hypothesen ziehen und ihr Antwortverhalten entsprechend anpassen. Da die Verwendung derselben Methode („Einheitsmethode“) zur Erhebung der Daten systematische aller Variablen verursachen kann, wird auch der Begriff Einheitsmethodenvarianz (engl. common-method variance) verwendet, der das Phänomen treffender beschreibt.

has abstract	In applied statistics, (e.g., applied to the social sciences and psychometrics), common-method variance (CMV) is the spurious "variance that is attributable to the measurement method rather than to the constructs the measures are assumed to represent" or equivalently as "systematic error variance shared among variables measured with and introduced as a function of the same method and/or source". For example, an electronic survey method might influence results for those who might be unfamiliar with an electronic survey interface differently than for those who might be familiar. If measures are affected by CMV or common-method bias, the intercorrelations among them can be inflated or deflated depending upon several factors. Although it is sometimes assumed that CMV affects all variables, evidence suggests that whether or not the correlation between two variables is affected by CMV is a function of both the method and the particular constructs being measured.
