Knowledge about air duct cleaning is in its early stages, so a blanket recommendation cannot be offered as to whether you should have your air ducts in your home cleaned. The U.S. Environmental Protection Agency (EPA) urges you to read this document in it entirety as it provides important information on the subject.
Historically, IQ is a score obtained by dividing a personâs mental age score, obtained by administering an intelligence test, by the personâs chronological age, both expressed in terms of years and months. The resulting fraction is multiplied by 100 to obtain the IQ score.
Put simply intelligence is mental horsepower. If you have more horsepower, you can do more, faster. If you have less horsepower, you can probably do as much, but it will take more time and energy. An IQ is a quick way to reference this. When you take an IQ test, you are compared to people who have taken the test before. Prior to the release of the test, the writers of the IQ test had several hundred, sometimes more than a thousand, people assessed.
