Moyle noted that NA was not simply a generic nuisance variable
but rather it played a complex and substantive role within the stress process.
Thus, the age of students should not be seen as a nuisance variable
in evaluating students' overall performance, expectations and satisfaction with a course.
In recent years, researchers examining relationships between work-related stressors and strains have typically controlled for the personality variable negative affectivity (NA) on the basis that NA may act either as a nuisance variable that artificially inflates correlations among self-reported stressors and strains (e.
In the case of NA, it does not allow researchers to determine whether correlations between self-reports of stressors and strains are biased because NA acts as a methodological nuisance variable or because its acts as a substantive variable.
The evidence presented in this study and others examining stressor-strain relations controlling for NA leads to an important tentative conclusion: it appears unlikely that NA acts as a nuisance variable that inflates correlations between individuals' self-reports of stressors and strains.
Coverage begins with research strategies and the control of nuisance variables
, experimental designs (an overview), and fundamental assumptions in analysis of variance.
p] are included to control for the effects of various nuisance variables
7 RANDOMIZED EXPERIMENTS HELP WITH UNKNOWN NUISANCE VARIABLES
6) Randomized experiments are important, not because they help wit the nuisance variables we think we know about, but because they enable us to cope with all those we don't know about.
As we have seen, the virtue of randomized experiments, as opposed to non-experimental surveys, is that they ensure that any further unidentified nuisance variables are uncorrelated with the treatment variable.
