felvariabler
Felvariabler, often translated as "error variables" or "nuisance variables," is a concept primarily found in statistical modeling and experimental design. In essence, a felvariabel is a variable that is not of primary interest to the researcher but can influence the outcome of an experiment or the reliability of a statistical model. Its presence can obscure the true relationship between independent and dependent variables or lead to misleading conclusions if not properly accounted for.
The main challenge with felvariabler is their potential to introduce bias or increase variance in the analysis.
Researchers employ various strategies to manage felvariabler. These include randomization, where experimental units are randomly assigned
