Extraneous variables are of most concern in experimental and quasi-experimental studies in which the researcher seeks to learn the effect of an independent variable on a dependent variable and must rule out the influence of other variables.An ethnographic study is not concerned with the effects of one variable on another; therefore,extraneous variables that may affect a variable are not usually discussed.A qualitative study is not concerned with the effects of one variable on another; therefore extraneous variables that may affect a variable are not usually discussed.A phenomenological study is not concerned with the effects of one variable on another; therefore extraneous variables that may affect a variable are not usually discussed.
