MATCHED GROUPS Meaning and
Definition
-
Matched groups refer to a research design used in experiments and observational studies where participants are placed into groups based on specific characteristics that are considered important or relevant to the study. These characteristics are commonly referred to as matching variables. The purpose of creating matched groups is to minimize potential bias and confounding variables that might affect the results of the study.
In a matched group design, participants are first divided into pairs or small groups based on their matching variables, such as age, gender, or socioeconomic status. Once the pairs or groups are created, one member is randomly assigned to the treatment group, while the other member serves as a control. This ensures that both groups are similar with respect to the matching variables, allowing for a more accurate comparison of the treatment effects.
This design is particularly useful in situations where a randomized controlled trial (RCT) is not feasible or ethical, such as in educational or medical studies. By matching participants based on relevant variables, researchers can control for potential confounding factors that may impact the results. This leads to a more reliable and valid comparison between the groups.
Matched groups are often utilized in fields such as psychology, education, and medicine to investigate the effects of certain interventions or treatments. The matched group design allows researchers to assess the causal relationship between the intervention and the outcomes of interest, while minimizing the influence of extraneous variables.

Etymology of MATCHED GROUPS
The etymology of the term "matched groups" can be understood by examining the origins of the individual words.
1. Matched: The word "matched" comes from the Old English word "macian" which means "to make" or "to correspond". It is derived from the Proto-Germanic word "makon" which has similar meanings. Over time, "macian" evolved into "match" in Middle English, retaining the same sense of corresponding or making something fit together.
2. Groups: The word "groups" originates from the Middle French word "groupe" or the Italian word "gruppo", both of which refer to a cluster or collection of things. These words have further roots in the Old Italian word "kruppo" meaning "body", and ultimately trace back to the Old High German word "kruppho" which means "cluster" or "bunch".
