A reference group is a scientific study of a few individuals. When scientists perform research studies, they compare the test results of the individuals with another test group.
Test Group when you test a project with a "GROUP"
In a criterion-referenced test, percentages are calculated based on mastery of specific content or skills against a predetermined standard or criteria. On the other hand, percentiles in a norm-referenced test indicate a test taker's rank compared to a specific group of test takers, showing the percentage of scores that are equal to or below a particular score.
Norma Reference Measurement and Reference Measurement Criteria generally is the most useful frame of reference to describe the level of knowledge and performance of students.
A group of individuals to which one desires to belong.
žNormative Reference group refers to groups that influence broadly and define values or behavior (Schiffman & Kanuk, 2010).
The group is called the test group or test subjects.
A test group is the group in an experiment to which the change is being applied and the control group is the same type of group in an experiment to which nothing is done to compare the changes in the test group to.
A criterion reference test measures individual knowledge and performance on the test and is generally viewed as a more accurate measure of learning. A norm reference test can generally be refered to as a standardized test. It measures the performance of one person on the test against an entire population of people. Test scores are delivered in percentiles rather than percentages. For example, someone who scored in the 87th percentile performed just as well or better than 87% of the people who have ever taken that particular test...ever!

Reference group theory, developed by Robert K. Merton, posits that individuals compare themselves to reference groups to evaluate their own social and personal standing. These reference groups can influence attitudes, behavior, and aspirations of individuals by setting norms and standards. Merton's framework highlights the role of social comparison in shaping an individual's self-concept and behavior.
Experimental group
A group test is a method of examining a set of individuals simultaneously for a specific trait or characteristic. This approach allows for efficient testing of a large number of people at once, often used in educational settings or for screening purposes. Group tests can provide quick feedback about the group's performance or proficiency levels.
