What is matching in research?

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.

What is a matched sample study?

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 “participant” is a member of the sample, and can be a person, object or thing.

What is a matched pair study?

A matched pairs design is a type of experimental design wherein study participants are matched based on key variables, or shared characteristics, relevant to the topic of the study. Then, one member of each pair is placed into the control group while the other is placed in the experimental group.

What is called match test in experimental research?

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).

What are matching methods?

To work around these issues researchers often employ what are called “matching methods”. This involves taking observational data, such as data from surveys, and matching people who have similar characteristics but different treatments.

What is an example of a matched group design?

[A good example of matched group designs are Twin Studies, which match subjects based on their genetic makeup; e.g. identical vs fraternal twins]. Matching is advantageous because we can increase the probability that our groups start out the same, at least on variables that we think matter.

What is Match data?

Data matching is the process of identifying and merging duplicate data records. This can be done across databases to ensure matching data is aligned. Data matching compares two sets of data to identify duplicate records.

What are matching questions?

Matching questions are made up of two lists of related items that students must pair up by deciding which item in the first list corresponds to an item in the second list. They are appealing to many teachers because they provide a compact way to test a great deal of information in a short amount of time.
