kontrollrühma
Kontrollrühma is a term used in the context of experimental research to denote the control group that does not receive the experimental intervention or receives a standard treatment. It serves as a baseline for comparison with the experimental group.
In randomized controlled studies, random assignment helps ensure that differences between groups reflect the intervention rather
Blinding and placebo controls are common methods to reduce bias; in non-drug research, an inactive or standard
Variants include negative controls, positive controls, and historical controls, each chosen to address different research questions.
Key considerations include randomization, sample size and power, handling attrition, and ethical issues related to withholding
By comparing outcomes across groups, researchers estimate the effect of the intervention and test whether observed
Kontrollrühma is thus central to experimental design, providing a baseline that helps attribute causal effects to
