From Wikipedia, the free encyclopedia. Matching is a statistical technique which is used to evaluate the effect of a treatment by comparing the treated and the non-treated units in an observational study or quasi-experiment (i.e. when the treatment is not randomly assigned).Click to see full answer. Also know, what is matching in case control studies?The idea in matching is to match upon a potential confounding variable in order to remove the confounding effect. In an analysis of a matched study design, only discordant pairs are used. A discordant pair occurs when the exposure status of case is different than the exposure status of the control.Furthermore, what is a matched sample? Matched samples (also called matched pairs, paired samples or dependent samples) are paired up so that the participants share every characteristic except for the one under investigation. A common use for matched pairs is to assign one individual to a treatment group and another to a control group. Also asked, what is a matching variable? One important type of experimental design is a matched-subjects design, also called a matched-group design, which is when subjects are matched on some variable that might be affecting the dependent variable and then split into two or more groups.What is a matched cohort study?Matching is a technique used to avoid confounding in a study design. In a cohort study this is done by ensuring an equal distribution among exposed and unexposed of the variables believed to be confounding. Nonetheless, a matched case-control study is suitable for confounders that are difficult to measure.
