A quiz is a form of game or mind sport, in which the players (as individuals or in teams) attempt to answer questions correctly. It is a game to test your knowledge about a certain subject. In some countries, a quiz is also a brief assessment used in education and similar fields to measure growth in knowledge, abilities, and/or skills.
Quizzes are usually scored in points and many quizzes are designed to determine a winner from a group of participants – usually the participant with the highest score. They may also involve eliminating those who get too many questions wrong, the winner being the last man standing.
Additionally, a personality quiz may be a series of multiple-choice questions about the respondent without right or wrong answers. The responses to these questions are tallied according to a key, and the result purports to reveal some quality of the respondent. This kind of "quiz" was originally popularized by women's magazines such as Cosmopolitan. They have since become common on the Internet, where the result page typically includes code which can be added to a blog entry to publicize the result. These postings are common on LiveJournal.
There are also many online quizzes. Many webmasters have quiz sections on their websites and forums; for instance, phpBB2 has one MOD (modification) which allows users to submit quizzes, called the Ultimate Quiz MOD.
The results of online quizzes are generally to be taken lightly, as they do not often reflect the true personality or relationship. They are also rarely psychometrically valid. However, they may occasion reflection on the subject of the quiz and provide a springboard for a person to explore his or her emotions, beliefs, or actions.
